Problems solved by technology

At present, general ultra-high temperature heat-resistant porcelain (temperature resistance up to 600 ℃) generally has the problem of glaze cracking. Although each product looks perfect from the macroscopic surface, many small micro-cracks will be found under the microscope. The existence of micro-cracks will cause the phenomenon of odors and other phenomena when the ceramic utensils are used when carrying different foods, and it will also affect the service life

preparation example Construction

[0021] The preparation method of the above-mentioned ceramic glaze according to an embodiment of the present invention includes the following steps: weighing and mixing each raw material according to the mass percentage to obtain the above-mentioned ceramic glaze.

[0022] The ceramic vessel according to an embodiment of the present invention, the raw materials for its preparation include the above-mentioned ceramic glaze. The preparation method of the ceramic vessel comprises the following steps: weighing the above-mentioned ceramic glaze and water according to the mass ratio of 1:1.1-1.3, mixing the ceramic glaze and water, grinding to obtain a slurry, and spraying the slurry on the ceramic body Fired to get ceramic vessels.

[0023] In one embodiment, the grinding specifically includes the following steps: putting the ceramic glaze and water into a ball mill and grinding until the median particle size (D50) is less than 3 μm. Reducing the particle size is conducive to furt...

Embodiment 1

[0030] Weigh each component raw material according to the following mass percentage: petalite 32%, spodumene 35%, kaolin 12%, white carbon black 5%, zirconium silicate 7%, calcined talc 5%, zinc oxide 2% and Double fly powder 2%. Put the raw materials of each component into the ball mill, add water according to the mass ratio of ceramic glaze to water 1:1.2, mix and ball mill for 3 hours, measure the particle size D50 with a laser particle size analyzer, and the D50 is required to be less than 3 μm. Then pass the product through a 325-mesh vibrating sieve, and circulate iron removal, and then adjust the specific gravity to 1.45g / cm 3 .

[0031] The slurry is sprayed onto the ceramic body by glaze spraying method, and then fired into the kiln to make ceramic samples. After the temperature difference of the ceramic samples exceeds 600°C, the glaze surface is lubricated and glossy. Observe the glaze surface of the ceramic samples under a microscope with a power of 200 times. Th...

Embodiment 2

[0033] Weigh each component raw material according to the following mass percentages: petalite 40%, spodumene 25%, kaolin 10%, white carbon black 10%, zirconium silicate 5%, calcined talc 5%, zinc oxide 3% and Double fly powder 2%. Put the raw materials of each component into the ball mill, add water according to the mass ratio of ceramic glaze to water 1:1.2, mix and ball mill for 3 hours, measure the particle size D50 with a laser particle size analyzer, and the D50 is required to be less than 3 μm. Then pass the product through a 325-mesh vibrating sieve, and circulate iron removal, and then adjust the specific gravity to 1.45g / cm 3 .

[0034] The slurry is sprayed onto the ceramic body by glaze spraying, and then fired into a kiln to make ceramic samples. After the ceramic samples are treated with a temperature difference of over 600°C, the glaze surface is lubricated and glossy. Observe the glaze surface of the ceramic samples under a microscope with a power of 200 times...

Abstract

The invention relates to a ceramic glaze, a ceramic ware and a preparation method of the ceramic ware. The ceramic glaze is prepared from the following raw materials by weight percent: 20%-40% of petalite, 20%-40% of spodumene, 10%-20% of kaolin, 5%-15% of white carbon black, 5%-10% of zirconium silicate, 5%-10% of calcined talcum, 1%-5% of zinc oxide and 1%-5% of calcium-magnesium powder. The ceramic glaze prepared from the raw materials in a specific combination and proportion has a relatively low linear expansion coefficient and relatively good adaptability and can be applied to a heat-proof ceramic ware with a temperature difference over 600 DEG C, a glaze surface is observed under a 200-time microscope, the crystal pattern of the glaze surface is complete, and the glaze surface is notcracked, so that the problem that the glaze surface is microcosmically cracked is solved; and meanwhile, by utilizing a rapid sintering process, the production cost is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a ceramic glaze, a ceramic vessel and a preparation method thereof. Background technique [0002] Ceramic is one of the most commonly used materials for cooking containers, such as the ceramic liner of a rice cooker. The food cooked by the ceramic liner has a better taste, which meets people's needs for food quality, and the surface of the ceramic itself is super hard and wear-resistant, and it also has strong acid, alkali and corrosion resistance. At present, general ultra-high temperature heat-resistant porcelain (temperature resistance up to 600 ℃) generally has the problem of glaze cracking. Although each product looks perfect from the macroscopic surface, many small micro-cracks will be found under the microscope. The existence of micro-cracks will cause the phenomenon of odors and other phenomena when the ceramic utensils are used when carrying different foods, and it wil...
