Novel ceramic snow glaze formula and firing process method

Abstract

The invention relates to the technical field of ceramic processing, and particularly discloses a novel ceramic snow glaze formula and a firing process method.The ceramic snow glaze is prepared from, by weight, 15-20% of aluminum oxide, 60-70% of silicon dioxide, 5-8% of ferric oxide, 5-10% of potassium oxide and 3-5% of sodium oxide.

Meanwhile, the optimized firing process ensures the stability of the ceramic structure and reduces the risk of cracks or deformation caused by thermal expansion and cold contraction.

Description

Technical Field

[0001] The invention belongs to the technical field of ceramic processing, and in particular relates to a novel ceramic snow glaze formula and a firing process method. Background Art

[0002] As a treasure of human civilization, ceramic art has a long history and exquisite craftsmanship. In the decoration and production process of ceramics, the selection of glazes and firing technology are crucial. Although traditional ceramic glazes and firing methods can produce colorful ceramic works, they still have limitations in certain specific effects, such as simulating natural snow scenes and snow-capped mountain landscapes.

[0003] Existing ceramic glaze formulas often fail to simultaneously meet the requirements of high whiteness, high transparency, and good melting properties. Especially when making ceramic works with snow mountain effects, traditional glazes often fail to form delicate and natural snowflake textures, and the colors are single and lack a sense of hierarchy. Summary of the invention

[0004] The purpose of the present invention is to provide a novel ceramic snow glaze formula and firing process method to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A novel ceramic snow glaze comprises the following raw materials in percentage: 15-20% of aluminum oxide, 60-70% of silicon dioxide, 5-8% of iron oxide, 5-10% of potassium oxide and 3-5% of sodium oxide.

[0007] Preferably, the raw materials include the following percentage components: 20% aluminum oxide, 60% silicon dioxide, 5% iron oxide, 10% potassium oxide and 5% sodium oxide.

[0008] Preferably, the raw materials include the following percentage components: 15% aluminum oxide, 70% silicon dioxide, 7% iron oxide, 5% potassium oxide and 3% sodium oxide.

[0009] A firing process method of a novel ceramic snow glaze formula comprises the following steps:

[0010] S1. Raw material pretreatment: calcine the raw materials at 300 degrees to remove moisture, organic matter and volatile impurities;

[0011] S2. Preparation of glaze: Grind the calcined raw materials into powder until they pass through a 200-mesh sieve, and mix the various powdered raw materials evenly according to the following percentage composition: 20% aluminum oxide content, 60% silicon dioxide content, 5% iron oxide content, 8% potassium oxide and 7% sodium oxide;

[0012] S3. Glazing: Sprinkle the prepared glaze powder evenly on the surface of the ceramic work with a thickness of 0.4mm to 0.8mm to form a glaze layer of a certain thickness. The powder sprinkling process should be carried out in a relatively dry and dust-free environment to prevent the glaze from getting damp or contaminated.

[0013] S4. Drying: After glazing, place the ceramic work in a dry and ventilated place to dry naturally or use low-temperature drying to accelerate the drying process;

[0014] S5. High-temperature firing: Place the dried ceramic work into a kiln for high-temperature firing. The heating process should be slow to avoid cracks or deformation of the ceramic work due to thermal expansion and contraction.

[0015] S6. Insulation treatment: When the kiln temperature reaches the firing temperature of 1250-1300℃, insulation treatment is carried out for 2-4 hours;

[0016] S7, cooling down: after the heat preservation is finished, the kiln temperature should be slowly lowered to room temperature and taken out;

[0017] S8. Quality inspection: Carry out quality inspection on fired ceramic snow glaze works.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] By precisely controlling the ratio of aluminum oxide, silicon dioxide, iron oxide, potassium oxide and sodium oxide in the formula, and optimizing the firing process, this patent successfully achieves the unique snow mountain effect of ceramic snow glaze. The glaze is delicate and smooth, with uniform color and rich layering, which greatly enhances the artistic value and ornamental value of ceramic works. At the same time, the addition of aluminum oxide in the formula significantly improves the hardness and wear resistance of the ceramic, making the ceramic snow glaze works more durable during use and less prone to wear or scratches. At the same time, the optimized firing process ensures the stability of the ceramic structure and reduces the risk of cracks or deformation caused by thermal expansion and contraction. DETAILED DESCRIPTION

[0023] A new firing process for ceramic snow glaze formula,

[0024] 1. Raw material pretreatment

[0025] Calcination: Calcine the raw materials at 300 degrees to remove moisture, organic matter and volatile impurities, and improve the purity and stability of the raw materials. This step is crucial to ensure the uniformity and fluidity of the subsequent glaze.

[0026] 2. Glaze Preparation

[0027] Grinding: Grind the calcined raw materials into powder and grind them to the standard of passing through a 200-mesh screen to ensure that the particles are fine and uniform. This helps to form a delicate texture and uniform color during the firing process.

[0028] Mixing: Mix various powdered raw materials evenly according to the formula ratio, the raw material ratio is 20% aluminum oxide content, 60% silicon dioxide content, 5% iron oxide content, 8% potassium oxide and 7% sodium oxide.

[0029] 3. Glazing

[0030] Evenly sprinkle powder: Sprinkle the prepared glaze powder evenly on the surface of the ceramic work to form a glaze layer of a certain thickness. The thickness is 0.4mm. During the powder sprinkling process, pay attention to controlling the thickness and uniformity of the glaze to avoid cracks or deformation during the firing process.

[0031] Drying: After glazing, place the ceramic work in a dry and ventilated place to dry naturally. The purpose of drying is to remove moisture from the glaze and prepare for subsequent firing.

[0032] 4. High temperature firing

[0033] Temperature control: The dried ceramic works are placed in a kiln for high-temperature firing. The heating process should be slow and even to avoid cracks or deformation of the ceramic works due to thermal expansion and contraction.

[0034] Insulation treatment: When the kiln temperature reaches the set firing temperature, it needs to be insulated for a period of time. The length of the insulation time depends on factors such as the size, shape and properties of the ceramic work and the glaze. The purpose of insulation is to make the glaze fully melt and flow, forming a delicate texture and uniform color.
