Description

Technical Field

[0001] The invention relates to the technical field of functional ceramic materials, in particular to a healthy ceramic material containing multiple elements such as strontium, phosphorus, barium, titanium and mica and a firing process thereof. Background Art

[0002] In recent years, as people are increasingly pursuing a healthy lifestyle, ceramic materials with functional and health value have gradually attracted widespread attention. This type of ceramic material is not only widely used in traditional tableware and building materials, but also endowed with new functionality, such as far-infrared emission, antibacterial properties, and water quality optimization. These functional characteristics have shown great potential in promoting human health and improving the quality of life. Therefore, research and development of healthy ceramic materials with multifunctional characteristics has become an important direction for the development of ceramic technology.

[0003] In the prior art, the research on functional ceramic materials mainly focuses on achieving their health functions by doping functional components (such as strontium, barium, titanium and other elements) into the matrix materials. These technologies usually form specific crystal phase structures (such as strontium barium titanate crystal phase and strontium phosphate crystal phase) by adjusting the raw material ratio and optimizing the firing process, thereby giving the ceramic materials the characteristics of far-infrared emission, antibacterial and mineral release. However, these technical solutions often show problems such as functional instability and uneven material performance in practical applications. In particular, in terms of water quality optimization and mineral release functions, it is difficult for the functional ceramics of the prior art to achieve stable and efficient effects.

[0004] The main problem with the existing technology is that the mineral release performance of ceramic materials in water is poor and unstable, and it is impossible to effectively supplement minerals such as strontium ions and barium ions that are beneficial to the human body. This problem is mainly due to the uneven distribution or incomplete generation of functional crystal phases (such as barium strontium titanate and strontium phosphate) in the material, as well as the failure to effectively control element migration and crystal phase stability during the firing process, resulting in insufficient mineral release and limited duration. Therefore, an optimized ceramic material and its preparation method are needed to significantly improve the mineral release capacity and solve the problem of insufficient performance of functional ceramics in the existing technology. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a healthy ceramic material containing multiple elements of strontium, phosphorus, barium, titanium, and mica and a firing process thereof, which solves the problem of poor and unstable mineral release performance of ceramic materials in the prior art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a healthy ceramic material containing multiple elements of strontium, phosphorus, barium, titanium, and mica, including: In order to maintain the functional strength of healthy ceramics, strontium uses natural strontium jade ore as the main raw material. After cleaning the strontium jade ore to remove mud and sand impurities, it is ground to 100 to 200 meshes to prepare strontium jade functional glaze; The proportion of strontium jade functional glazes in the total glazes is more than 50%, and the rest is other glazes; The strontium jade mixed glaze is evenly sprayed or dipped onto the surface of a ceramic body made of kaolin, purple clay or other high-temperature resistant clay, and fired at high temperature to form a healthy ceramic material with small molecular cluster water conversion function.

[0007] The firing process of the healthy ceramic material containing multiple elements of strontium, phosphorus, barium, titanium and mica includes the following steps: Step 1: clean the strontium jade ore to remove mud and sand impurities, and grind the strontium jade ore to 100 to 200 meshes using a special glaze grinder to obtain a strontium jade functional glaze; According to the need, the strontium jade functional glaze is evenly mixed with other glazes in proportion to prepare a strontium jade mixed glaze; Step 2: evenly apply the strontium jade mixed glaze on the surface of the dried or naturally dried ceramic body by spraying or dipping; Step 3: Firing: The ceramic body coated with glaze is placed in an electric kiln, a wood kiln or a natural gas kiln, heated to 1100℃~1240℃, and fired at this temperature; The firing temperature generally does not exceed 1300°C, and the temperature can be adjusted according to product requirements to obtain ceramic products with different densities and functions.

[0008] Preferably, the strontium jade functional glaze imparts health functions to the ceramic material through a small molecular cluster water conversion mechanism, wherein the small molecular cluster water conversion comes from the natural strontium, barium, titanium and mica multi-element energy minerals in the strontium jade ore that can improve the water molecule structure.

[0009] Preferably, the preparation of strontium jade glaze adopts a direct grinding process, grinding natural strontium jade ore to 100 mesh to 200 mesh without extracting or separating the functional elements therein; The glaze coating can be applied by spraying or dipping to achieve glaze layers of different thicknesses according to product requirements; After firing, the temperature is quickly lowered to 800°C and then slowly cooled to room temperature.

[0010] The present invention provides a healthy ceramic material containing multiple elements of strontium, phosphorus, barium, titanium, and mica and a firing process thereof. It has the following beneficial effects: The present invention uses natural strontium jade ore as the main raw material, wherein strontium, phosphorus, barium, titanium and mica minerals can effectively release functional ions through synergistic action during the firing process. These ions change the arrangement of water molecules through ion exchange and physical action, generate small molecular cluster water, help improve the bioavailability of water, and enhance the health effect of drinking water. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic diagram of the method flow of the present invention. DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] Embodiment 1: Please see attached Figure 1 The embodiment of the present invention provides a healthy ceramic material containing multiple elements of strontium, phosphorus, barium, titanium, mica and a firing process thereof, including: First, natural strontium jade ore is selected as the main raw material. Strontium jade ore is rich in strontium, barium, titanium and mica minerals. These components can improve the physical properties of ceramic materials and give them health functions through synergistic effects during high-temperature firing. The strontium jade ore needs to go through a cleaning process to remove mud and impurities on the surface to ensure the purity of the raw material. The cleaned ore is crushed with a special glaze grinder and ground to a particle size range of 100 to 200 mesh to ensure that it can be evenly dispersed in the glaze and improve the release efficiency of functional elements. The powder obtained in this step is the strontium jade functional glaze.

[0014] The strontium jade functional glaze is mixed with other auxiliary glazes (such as lead glaze, alkaline glaze or common popular glazes) in a proportion that the strontium jade functional glaze accounts for more than 50% of the total glaze and other glazes account for less than 50%. The main function of the auxiliary glaze is to improve the color, gloss and fluidity of the ceramic glaze, and at the same time play an auxiliary role in health functions. After mixing, it is fully mixed by high-speed stirring equipment to obtain a homogenized strontium jade mixed glaze.

[0015] The raw materials of ceramic green bodies can be selected from kaolin, purple sand or other high temperature resistant clay materials. These materials have good plasticity and high temperature stability and are suitable for preparing different types of ceramic products. The green body raw materials are prepared into the desired shape through molding, slip injection molding or manual molding. The green body after molding needs to go through natural drying or low temperature drying process to make its surface dry and crack-free, so as to prepare for the subsequent glaze coating.

[0016] The prepared strontium jade mixed glaze is evenly applied to the surface of the dried ceramic body by spraying or dipping. The thickness of the glaze coating can be adjusted according to the functional requirements of the product, usually controlled between 0.1 and 0.3 mm to ensure the uniformity of the glaze layer and the release effect of the functional elements. For ceramic bodies with complex shapes, the spraying process can be used first; for bodies produced in large quantities, the dipping process is more efficient. After the glaze is applied, the body needs to be naturally dried or dried at low temperature again to ensure that the glaze is evenly attached and does not sag.

[0017] The ceramic body coated with glaze is placed in an electric kiln, a wood kiln or a natural gas kiln for firing. During the firing process, a step-by-step heating method is required: from room temperature to 500°C, the temperature is slowly raised to fully remove the moisture inside the body; from 500°C to 1100°C, the heating speed is accelerated to promote the initial sintering of the body and glaze; at the high temperature stage of 1100°C to 1240°C, the temperature is kept for 1.5 to 2 hours to complete the melting of the glaze and the densification of the body. The maximum firing temperature shall not exceed 1300°C to avoid excessive fluidity of the glaze or deformation of the body that affects the quality of the finished product.

[0018] After firing, the temperature needs to be quickly lowered to 800°C. This process can avoid the generation of high-temperature cracks and stabilize the crystalline structure of the glaze. Then the temperature is slowly lowered to room temperature at a rate of no more than 0.5°C / minute. This slow cooling process ensures the bonding strength between the glaze and the body, while further enhancing the density and smoothness of the glaze.

[0019] The ceramic material prepared by the above process has good health functions, and its health functions mainly come from strontium, phosphorus, barium, titanium and mica minerals in strontium jade ore. These minerals are released into the ceramic glaze in the form of ions during the firing process, and change the arrangement of water molecules through ion exchange and physical action to generate small molecular clusters of water, thereby improving the bioavailability of water. The ceramic material is suitable for the production of various functional living utensils, such as ceramic pots, ceramic cups, ceramic bowls, ceramic pots, as well as health functional ceramic decorative panels and functional ceramic tiles. At the same time, different types of auxiliary glazes can be added to the glaze to achieve different colors and gloss effects, providing diversified choices for the appearance design of ceramic products.

[0020] In addition, ceramic materials of different densities can be produced by adjusting the firing temperature and glaze ratio. For example, by increasing the firing temperature (close to 1240°C), high-density healthy ceramic tableware with strong high-temperature resistance can be prepared; by lowering the firing temperature (about 1100°C to 1200°C), medium- and low-density functional ceramic tiles and plates can be prepared to meet the needs of light weight and decoration. The final product has a dense and smooth glaze surface, excellent wear resistance, crack resistance and health functions, and meets consumers' dual needs for functionality and aesthetics.

[0021] Embodiment 2: In order to verify the effect of firing temperature on the performance of healthy ceramic materials, in this embodiment, the firing temperature in Example 1 is adjusted from 1100°C to 1240°C to 1000°C to 1100°C, and other process conditions remain completely the same. The specific operation steps are as follows: Step 1: Raw material preparation Natural strontium jade ore is selected as the main raw material, and the surface mud, sand and impurities are cleaned to ensure the purity of the raw material.

[0022] The cleaned strontium jade ore is crushed into 100 mesh to 200 mesh using a special glaze grinder to obtain a strontium jade functional glaze.

[0023] The strontium jade functional glaze is mixed with other auxiliary glazes (such as lead glaze or alkaline glaze) in a proportion of ≥50%, and stirred evenly using a high-speed stirring device to prepare a strontium jade mixed glaze.

[0024] Step 2: Ceramic body preparation Using high temperature resistant clay such as kaolin or purple sand as raw materials, ceramic bodies are prepared by compression molding. The shapes include ceramic cups, ceramic pots, bowls and ceramic plates.

[0025] The formed body is naturally dried for 12 hours to ensure that the surface is dry and free of cracks.

[0026] Step 3: Glaze application The prepared strontium jade mixed glaze is evenly coated on the surface of the dry ceramic body by spraying, and the thickness of the glaze layer is controlled to be about 0.2 mm.

[0027] The coated body is allowed to dry naturally again for 4 hours to ensure that the glaze is evenly adhered.

[0028] Step 4: Firing The ceramic body coated with glaze is placed in an electric kiln for firing.

[0029] Adjust the firing temperature range to 1000℃~1100℃, and adopt the following heating scheme: Room temperature to 500°C: heating at a rate of 5°C / min, mainly to remove moisture from the body; 500℃ to 1000℃: Raise the temperature at a rate of 10℃ / min to promote the initial melting of the glaze; The holding temperature was set at 1000°C to 1100°C, and the holding time was 1.5 hours.

[0030] After firing, the temperature was quickly lowered to 800°C and then slowly cooled to room temperature at a rate of 0.5°C / min.

[0031] Experimental Example 1: In order to verify the effects of different firing temperatures on the performance of healthy ceramic materials containing multiple elements of strontium, phosphorus, barium, titanium and mica in Example 1 and Example 2, a comparative experiment was conducted. In the two groups of experiments, except for the different firing temperatures, the other process conditions were exactly the same.

[0032] Experimental conditions Raw materials: natural strontium jade ore, kaolin, purple sand, high temperature resistant wet clay; The proportion of strontium jade functional glaze: ≥50%, the rest is auxiliary glaze; Blank forming method: compression molding; Glaze coating method: spraying, glaze layer thickness is 0.2 mm; Firing temperature: Embodiment 1: 1100°C to 1240°C; Embodiment 2: 1000°C to 1100°C; Cooling method: Rapidly cool to 800°C, then slowly cool to room temperature at 0.5°C / min.

[0033] Test indicators Appearance performance: glaze gloss, number of pores, surface uniformity; Health function: Changes in water molecule size (Hz); Mechanical properties: glaze hardness (Mohs) and crack resistance; Yield rate: the proportion of qualified samples out of 100 samples.

[0034] Table 1: Experimental data summary Experimental analysis Appearance performance comparison In Example 1, when the firing temperature is 1100°C to 1240°C, the glaze is fully melted, the glaze surface has high gloss, good density, and a uniform surface without defects; however, in Example 2, due to insufficient firing temperature, the glaze is not completely melted, resulting in a decrease in glaze gloss, an increase in the number of pores, and an uneven surface.

[0035] Health function comparison Example 1 can reduce the size of water molecule clusters to 110 Hz, which is significantly better than 160 Hz of Example 2. This shows that at a higher firing temperature, functional elements such as strontium and barium are released more fully, and the water conversion function of small molecule clusters is stronger.

[0036] Mechanical properties comparison The glaze hardness of Example 1 is 8 Mohs, the crack resistance is good, and the fired product has no cracks; while the glaze hardness of Example 2 is 6 Mohs, the crack resistance is poor, and some samples have fine cracks during the test.

[0037] Yield Comparison The yield rate of Example 1 is 96%, which is significantly higher than 85% of Example 2. This shows that a higher firing temperature can effectively reduce the scrap rate and improve production efficiency.

[0038] The experimental results show that the firing temperature in Example 1 (1100°C to 1240°C) is significantly better than that in Example 2 (1000°C to 1100°C), and can achieve the best balance in terms of glaze gloss, health function, mechanical properties and yield. Therefore, the process conditions in Example 1 are the optimal solution.

[0039] Example 3: Preparation method of functional ceramic disk In order to further verify the effect of firing temperature on the performance of healthy ceramic materials containing multiple elements of strontium, phosphorus, barium, titanium and mica, in Example 3, the firing temperature of Example 1 was adjusted from 1100°C to 1240°C to 1240°C to 1300°C, and other process conditions remained completely consistent.

[0040] Raw material preparation After cleaning and removing mud and sand impurities from natural strontium jade ore, it is crushed to 100 to 200 meshes using a special glaze grinder to prepare strontium jade functional glaze. The strontium jade functional glaze is mixed with other auxiliary glazes in a ratio of ≥50%, fully stirred and set aside.

[0041] Ceramic body preparation Kaolin and purple clay are used as the main raw materials to prepare ceramic bodies in the shape of ceramic cups and ceramic plates through a compression molding process. After the body is formed, it is naturally dried for 12 hours to ensure that the surface is dry and crack-free.

[0042] Glaze coating Spray the strontium jade mixed glaze evenly on the surface of the dried body, and control the thickness of the glaze layer to 0.2 mm. After coating, let it dry naturally for 4 hours.

[0043] Firing process The ceramic body coated with glaze is placed in an electric kiln for firing, and the firing temperature is adjusted to 1240℃~1300℃. The firing process is divided into the following stages: Initial heating: room temperature to 500°C, heating at a rate of 5°C / min; Mid-term heating: 500℃ to 1240℃, heating at a rate of 10℃ / min; High temperature insulation: 1240℃~1300℃ insulation for 1.5 hours to promote complete melting of glaze and formation of crystal phase.

[0044] Cooling process After firing, the temperature was quickly lowered to 800°C and then slowly cooled to room temperature at a rate of 0.5°C / min.

[0045] Performance Testing Record the product's appearance performance, health functions, mechanical properties and yield rate.

[0046] Experimental Example 2 In order to verify whether the firing temperature of Example 3 is better than that of Example 1, and to explore the effect of high temperature firing on the performance of ceramic materials, a comparative experiment was conducted. The following is a summary table of experimental data: Table 2: Experimental data table Experimental analysis Appearance performance comparison When the firing temperature of Example 3 was raised to 1240°C to 1300°C, the glaze melting effect was more complete, the surface was completely densified, and the glaze layer had no pores. However, as the temperature was close to the upper limit of the glaze fluidity, some samples had sag and accumulation on the glaze surface, affecting the uniformity of the appearance.

[0047] Health function comparison The size of the water molecule clusters in Example 3 was reduced to 105 Hz, which was slightly higher than 110 Hz in Example 1, indicating that higher temperatures promoted the release of functional elements (such as strontium and barium).

[0048] Mechanical properties comparison The glaze hardness of Example 3 reaches 9 Mohs, which is better than 8 Mohs of Example 1. However, during the high-temperature insulation stage, cracks appear in local areas, affecting the overall anti-cracking performance.

[0049] Yield Comparison The yield rate of Example 3 is 88%, which is lower than 96% of Example 1. Although high temperature firing improves some properties, it is more likely to cause sagging and cracks, increasing the scrap rate.

[0050] The experimental results show that although the firing temperature of Example 3 (1240℃~1300℃) further improves the health function and mechanical hardness, it also brings problems such as glaze sagging and increased cracks, significantly reducing the yield rate and appearance uniformity. Therefore, the firing temperature range (1100℃~1240℃) used in Example 1 can better balance the glaze performance and production efficiency, and is the best process condition for achieving the optimal performance of health functional ceramic materials.

[0051] Embodiment 4: In order to further verify the effect of firing temperature on the performance of healthy ceramic materials containing multiple elements of strontium, phosphorus, barium, titanium and mica, in Example 4, the firing temperature of Example 1 was adjusted from 1100°C to 1240°C to 900°C to 1000°C, and other process conditions remained completely consistent.

[0052] Raw material preparation After cleaning to remove mud, sand and impurities, the natural strontium jade ore is crushed to 100 to 200 meshes using a special glaze grinder to prepare strontium jade functional glaze. The strontium jade functional glaze is mixed with other auxiliary glazes in a ratio of ≥50%, stirred evenly and set aside.

[0053] Ceramic body preparation Using kaolin and purple sand as the main raw materials, the ceramic green body is prepared through the molding process, and the shapes include ceramic cups and ceramic plates. After the green body is formed, it is naturally dried for 12 hours to ensure that the surface is dry and free of cracks.

[0054] Glaze coating The prepared strontium jade mixed glaze is evenly sprayed on the surface of the dried body, and the thickness of the glaze layer is controlled to be 0.2 mm. After coating, it is naturally dried again for 4 hours.

[0055] Firing process The ceramic body coated with glaze is placed in an electric kiln for firing, and the firing temperature is adjusted to 900℃~1000℃. The firing process is divided into the following stages: Initial heating: room temperature to 500°C, heating at a rate of 5°C / min; Mid-term heating: 500℃ to 900℃, heating at a rate of 10℃ / min; High temperature insulation: 900℃~1000℃ insulation for 1.5 hours to promote glaze melting.

[0056] Cooling process After firing, the temperature was quickly lowered to 800°C and then slowly cooled to room temperature at a rate of 0.5°C / min.

[0057] Performance Testing Record the product's appearance performance, health functions, mechanical properties and yield rate.

[0058] Experimental Example 3: In order to verify the effects of the firing temperature in Example 4 (900°C to 1000°C) and Example 1 (1100°C to 1240°C) on the performance of the healthy ceramic material containing multiple elements of strontium phosphorus barium titanium mica, a comparative experiment was conducted. The specific experimental steps are as follows: Step 1: Raw material preparation Natural strontium jade ore is cleaned to remove mud, sand and impurities to ensure the purity of the raw materials.

[0059] The strontium jade ore is crushed into 100 mesh to 200 mesh using a special glaze grinder to serve as a strontium jade functional glaze.

[0060] According to the proportion, the strontium jade functional glaze should account for ≥ 50% of the total glaze, and the rest is auxiliary glaze (such as lead glaze or alkaline glaze). Use high-speed stirring equipment to evenly mix the glazes for later use.

[0061] Step 2: Ceramic body preparation Using kaolin and purple sand as the main raw materials, the ceramic body is prepared through a compression molding process. The molded products include two shapes: ceramic cups and ceramic plates.

[0062] After the blank is formed, it is naturally dried for 12 hours to ensure that the surface of the blank is dry and free of cracks.

[0063] Step 3: Glaze application Use spraying equipment to evenly coat the strontium jade mixed glaze on the surface of the dried body, and control the glaze thickness to 0.2 mm.

[0064] The coated body is allowed to dry naturally for another 4 hours to ensure that the glaze adheres evenly and without sagging.

[0065] Step 4: Firing process Embodiment 1: The glaze-coated ceramic body is placed in an electric kiln and fired at a temperature of 1100°C to 1240°C.

[0066] The heating process is divided into three stages: Room temperature to 500°C: Raise the temperature at a rate of 5°C / min to remove moisture from the body; 500℃ to 1100℃: Raise the temperature at a rate of 10℃ / min to promote the initial melting of the glaze; 1100℃~1240℃: Keep at high temperature for 1.5 hours to ensure that the glaze is completely melted and forms a dense glaze surface.

[0067] After firing, the temperature was quickly lowered to 800°C and then slowly cooled to room temperature at a rate of 0.5°C / min.

[0068] Embodiment 4: The glaze-coated ceramic body is placed in an electric kiln and fired at a temperature of 900°C to 1000°C.

[0069] The heating process is divided into three stages: Room temperature to 500°C: Raise the temperature at a rate of 5°C / min to remove moisture from the body; 500℃ to 900℃: Raise the temperature at a rate of 10℃ / min to promote the initial melting of the glaze; 900℃~1000℃: Keep at high temperature for 1.5 hours to ensure that the glaze reaches a certain degree of melting.

[0070] After firing, the temperature was quickly lowered to 800°C and then slowly cooled to room temperature at a rate of 0.5°C / min.

[0071] Step 5: Performance Testing Appearance performance test: Observe the glaze gloss, surface uniformity and number of pores, and record whether there are cracks or other defects.

[0072] Health function test: Use a water molecule cluster tester to detect the effect of ceramic samples on the water molecule structure and record the change in the size of water molecule clusters (Hz).

[0073] Mechanical properties test: Test the hardness (Mohs hardness) and crack resistance of the glaze, and record whether the sample has cracks.

[0074] Yield rate statistics: In each set of experiments, 100 samples were tested, the number of qualified samples that met the quality standards was counted, and the yield was calculated.

[0075] Table 3: Experimental data comparison table Experimental analysis Appearance performance comparison The firing temperature of the first embodiment can make the glaze fully melt, forming a high-gloss, uniform and dense glaze surface with no cracks and pores on the surface.

[0076] Example 4 Due to insufficient firing temperature, the glaze was not completely melted, the glaze surface had low gloss and was rough, the number of pores increased significantly, and the surface unevenness was more obvious.

[0077] Health function comparison The water molecule cluster size of Example 1 is 110 Hz, which is significantly better than 180 Hz of Example 4, indicating that the lower firing temperature cannot fully release functional elements such as strontium and barium, and the health function is greatly reduced.

[0078] Mechanical properties comparison The glaze hardness of Example 1 is 8 Mohs, which has good scratch resistance and crack resistance; the glaze hardness of Example 4 is only 5 Mohs, the glaze is soft and easy to scratch, and obvious cracks appear.

[0079] Yield Comparison The yield rate of Example 1 is 96%, which is significantly higher than 75% of Example 4. The lower firing temperature leads to an increase in the scrap rate, and the problems of glaze cracks and pores are particularly prominent.

[0080] Through comparative experiments, it was found that the firing temperature (900℃~1000℃) in Example 4 significantly reduced the appearance performance, health function, mechanical properties and yield rate of the healthy ceramic material. Therefore, the firing temperature range (1100℃~1240℃) used in Example 1 can better balance the glaze density, functionality and production efficiency, and is the optimal process condition.

[0081] Embodiment 5: In order to verify the effect of firing time on the performance of healthy ceramic materials containing multiple elements of strontium, phosphorus, barium, titanium and mica, in Example 5, the high temperature holding time of Example 1 was adjusted from 1.5 hours to 0.5 hours, and other process conditions remained completely consistent.

[0082] Raw material preparation After the natural strontium jade ore is cleaned to remove mud, sand and impurities, it is crushed to 100 mesh to 200 mesh using a special glaze grinder to prepare a strontium jade functional glaze.

[0083] Strontium jade functional glaze is mixed with other auxiliary glazes in a proportion of ≥50%, stirred thoroughly and set aside.

[0084] Ceramic body preparation Kaolin and purple sand are used as main raw materials, and ceramic bodies are prepared by compression molding in the shape of ceramic cups and ceramic plates.

[0085] The formed body is naturally dried for 12 hours to ensure that the surface of the body is dry and free of cracks.

[0086] Glaze coating The prepared strontium jade mixed glaze is evenly sprayed on the surface of the dried body, and the thickness of the glaze is controlled to be 0.2 mm.

[0087] The coated body was allowed to dry naturally for 4 hours again.

[0088] Firing process The firing temperature was maintained at 1100°C to 1240°C, and the holding time was adjusted to 0.5 hours.

[0089] The heating process is divided into three stages: Room temperature to 500°C: increase the temperature at a rate of 5°C / min; 500℃ to 1100℃: heating at a rate of 10℃ / min; 1100℃~1240℃: high temperature insulation for 0.5 hours.

[0090] After firing, the temperature was quickly lowered to 800°C and then slowly cooled to room temperature at a rate of 0.5°C / min.

[0091] Performance Testing Test appearance performance, health function, mechanical properties and yield rate.

[0092] Experimental Example 4: The effects of Example 5 (high temperature insulation time of 0.5 hours) and Example 1 (high temperature insulation time of 1.5 hours) on the performance of healthy ceramic materials containing multiple elements of strontium, phosphorus, barium, titanium and mica were verified.

[0093] Experimental procedures Raw material preparation Select natural strontium jade ore and clean it to remove mud, sand and impurities.

[0094] The strontium jade ore is crushed into 100 mesh to 200 mesh by using a special glaze grinding machine to prepare a strontium jade functional glaze.

[0095] Mix according to the proportion: strontium jade functional glaze ≥ 50%, the rest is auxiliary glaze, stir evenly and set aside.

[0096] Ceramic body preparation Kaolin and purple sand are used as the main raw materials, and the ceramic body is prepared through a compression molding process. The molded products include ceramic cups and ceramic plates.

[0097] After the blank is formed, it is naturally dried for 12 hours to ensure that the surface is dry and free of cracks.

[0098] Glaze coating Use spraying equipment to evenly spray the strontium jade mixed glaze on the surface of the dried body, and control the glaze thickness to 0.2 mm.

[0099] Allow to dry naturally for 4 hours after application to ensure that the glaze adheres evenly and does not sag.

[0100] Firing process Example 1: The high temperature holding time is 1.5 hours, the firing temperature is 1100°C to 1240°C, and the heating scheme is as follows: Room temperature to 500°C: increase the temperature at a rate of 5°C / min; 500℃ to 1100℃: heating at a rate of 10℃ / min; 1100℃~1240℃: Keep at high temperature for 1.5 hours to ensure that the glaze is fully melted.

[0101] Embodiment 5: The high temperature holding time is 0.5 hours, the firing temperature is also 1100° C. to 1240° C., the heating scheme is the same, but the high temperature holding stage is shortened to 0.5 hours.

[0102] After firing, the temperature was rapidly lowered to 800°C and then slowly lowered to room temperature at a rate of 0.5°C / min.

[0103] Performance Testing Appearance test: observe the gloss, uniformity and number of pores on the glaze.

[0104] Health function test: Use a water molecule cluster tester to detect the impact of ceramic samples on the water molecule structure and record the size of water molecule clusters (Hz).

[0105] Mechanical property test: Test the hardness (Mohs hardness) and crack resistance of the glaze.

[0106] Yield rate statistics: 100 samples are tested in each experiment, the number of qualified samples is counted and the yield rate is calculated.

[0107] Table 4: Experimental data table The experimental results show that shortening the high temperature holding time to 0.5 hours in Example 5 results in insufficient melting of the glaze, affecting the gloss and uniformity of the glaze surface; the health function and mechanical properties are reduced, and the yield rate is significantly reduced. Therefore, the 1.5-hour holding time in Example 1 can achieve the best effect.

[0108] Embodiment 6: In order to verify the effect of longer high-temperature insulation time on healthy ceramic materials containing multiple elements of strontium, phosphorus, barium, titanium, and mica, in Example 6, the high-temperature insulation time of Example 1 was adjusted from 1.5 hours to 3 hours, and other process conditions remained the same.

[0109] Specific steps The steps of raw material preparation, ceramic body preparation and glaze coating are the same as those in Example 1.

[0110] Firing process The firing temperature is 1100°C to 1240°C, and the holding time is adjusted to 3 hours.

[0111] The heating process is divided into three stages, which are consistent with the first embodiment: Room temperature to 500°C: increase the temperature at a rate of 5°C / min; 500℃ to 1100℃: heating at a rate of 10℃ / min; 1100℃~1240℃: high temperature insulation for 3 hours.

[0112] After firing, the temperature was quickly lowered to 800°C and then slowly cooled to room temperature at a rate of 0.5°C / min.

[0113] Performance Testing Test appearance performance, health function, mechanical properties and yield Experimental Example 5: The effects of Example 6 (high temperature insulation time of 3 hours) and Example 1 (high temperature insulation time of 1.5 hours) on the performance of healthy ceramic materials containing multiple elements of strontium, phosphorus, barium, titanium and mica were verified.

[0114] Experimental procedures Raw material preparation The natural strontium jade ore is cleaned to remove mud, sand and impurities, and the strontium jade ore is crushed to 100 mesh to 200 mesh using a special glaze grinder to prepare a strontium jade functional glaze.

[0115] Strontium jade functional glaze and auxiliary glaze are mixed in a ratio of ≥50%, stirred evenly and set aside.

[0116] Ceramic body preparation Kaolin and purple sand are used as raw materials, and the ceramic body is prepared through a compression molding process. The molded products include ceramic cups and ceramic plates.

[0117] After forming, let it dry naturally for 12 hours to ensure that the surface of the blank is dry and free of cracks.

[0118] Glaze coating Use spraying equipment to evenly coat the strontium jade mixed glaze on the surface of the dried body, and the thickness of the glaze layer is controlled at 0.2 mm.

[0119] Allow to dry naturally for 4 hours after application to ensure even adhesion of the glaze.

[0120] Firing process Example 1: The high temperature holding time is 1.5 hours, the firing temperature is 1100°C to 1240°C, and the heating scheme is as follows: Room temperature to 500°C: increase the temperature at a rate of 5°C / min; 500℃ to 1100℃: heating at a rate of 10℃ / min; 1100℃~1240℃: Keep at high temperature for 1.5 hours to ensure that the glaze is fully melted.

[0121] Example 6: The high temperature holding time is 3 hours, the firing temperature is also 1100° C. to 1240° C., the heating scheme is the same, but the high temperature holding stage is extended to 3 hours.

[0122] After firing, the temperature was rapidly lowered to 800°C and then slowly lowered to room temperature at a rate of 0.5°C / min.

[0123] Performance Testing Appearance test: observe the gloss, uniformity and number of pores on the glaze.

[0124] Health function test: Use a water molecule cluster tester to detect the impact of ceramic samples on the water molecule structure and record the size of water molecule clusters (Hz).

[0125] Mechanical property test: Test the hardness (Mohs hardness) and crack resistance of the glaze.

[0126] Yield rate statistics: 100 samples are tested in each experiment, the number of qualified samples is counted and the yield rate is calculated.

[0127] Table 5: Experimental data table The experimental results show that extending the high temperature holding time to 3 hours in Example 6 further improves the hardness and functionality of the glaze, but too long a holding time leads to significant glaze sagging and accumulation, increased local high temperature cracks, and decreased yield. Therefore, the 1.5-hour holding time in Example 1 is the best solution to achieve the optimal performance of the ceramic material.

[0136] After firing, the temperature was quickly lowered to 800°C and then slowly cooled to room temperature at a rate of 0.5°C / min.

[0137] Performance Testing Appearance test: observe the gloss, uniformity and number of pores on the glaze.

[0146] Glaze coating The prepared strontium jade mixed glaze is evenly sprayed or dipped on the surface of dry ceramic utensils, plates and tile bodies, and the thickness of the glaze layer is controlled at 0.3 mm.

[0147] The coated body is allowed to dry naturally again for 4 to 6 hours to ensure that the glaze adheres evenly.
