Embodiment 1

[0039] A preparation method and application of a snowflake-like devitrified ceramic glaze, comprising the following steps:

[0040] Step 1, egg shell calcined powder, barium carbonate, quartz, dredged bottom mud dry powder, nano-alumina powder are according to each mass ratio (egg shell calcined powder: barium carbonate: quartz: dredged bottom mud dry powder: nano-alumina powder=( 30: 25: 35: 3.0: 7) were weighed and prepared as JS glaze; among them, egg shell calcined powder was obtained by mechanically crushing egg shells and calcining at high temperature at 650°C for 1.5 h; dredging The dried sediment powder is obtained by passing the dredged sediment through a 200-mesh sieve and fully drying it in a blast drying oven. The drying temperature is 220 °C and the drying time is 5 h; the particle size of the nano-alumina powder is 100 nanometers .

[0041] Step 2. Mix JS glaze, water, and agate balls in a mass ratio of 1.0:1.6:1.6, and then use a planetary ball mill for ball mi...

Abstract

The invention discloses a preparation method and application of snowflake-shaped crystallized ceramic glaze. Specifically, egg shell calcined powder, barium carbonate, quartz, dredged sediment dry powder and nanometer aluminum oxide powder are made into glaze according to a certain proportion, the proportion of the glaze, water and grinding balls is further regulated and controlled, the glaze is made into glaze slip after planetary ball milling and sieving treatment, and the snowflake-shaped crystallized ceramic glaze is made into glaze slurry. The glaze slurry is applied to the surface of a biscuit firing ceramic biscuit by adopting a glaze dipping method, the glazed biscuit is dried and then placed in a muffle furnace to be fired, and a ceramic glaze product with snowflake-shaped crystalization is obtained.

Description

technical field [0001] The invention relates to the technical field of ceramic glaze preparation, in particular to a preparation method and application of a snowflake crystallization ceramic glaze. Background technique [0002] Since the Shang Dynasty, pottery began to have glaze, which has a history of thousands of years. Ceramic glaze is a vitreous layer attached to the surface of the ceramic body. Ceramic glaze has the functions of airtight and watertight. Ceramic glazes of different colors and textures also increase the beauty of ceramic utensils, and ceramic glazes can prevent utensils from being polluted and easily cleaning. With the rapid development of society, people's pursuit of new ceramic glazes is becoming more and more urgent. At present, the ceramic glazes on the market are not innovative enough and most of them use a reducing atmosphere in the firing process, which has problems of explosion and environmental pollution. Contents of the invention [0003] I...
