Abstract

The invention discloses a cobalt carbonate high-temperature purple ceramic glaze and a preparation method thereof and belongs to the field of ceramics. The cobalt carbonate high-temperature purple ceramic glaze is prepared by firstly preparing a cobalt carbonate high-temperature purple ceramic glaze material and by further performing glazing and high-temperature sintering. The cobalt carbonate high-temperature purple ceramic glaze material comprises the following raw materials in percentage by mass: 30-35% of nepheline syenite, 6-7% of chalk powder, 14.5-18.5% of silicon dioxide, 18-25% of calcined kaolin, 12-15% of dolomite, 4-7% of zinc oxide and 1-3% of cobalt carbonate. By adopting the method, the ceramic glaze has a color effect of light lavender purple and a surface smooth effect athigh temperature, and meanwhile physical and chemical property stability of the ceramic glaze is achieved. The formula of the glaze is adjusted and tested for multiple times for a long time, long-termtests at minus 30 DEG C show that no glaze cracking or dropping phenomenon is caused, and the glaze is resistant to common acid / alkali corrosion.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a cobalt carbonate high-temperature purple ceramic glaze and a preparation method thereof. Background technique [0002] Ceramic glaze is an important raw material that must be used in the production of ceramics. It has a strong protective effect on the ceramic body. At the same time, the physical properties of silicate make the glass enamel on the ceramic surface effectively resistant to acid and alkali corrosion. Very good antibacterial properties. Ordinary ceramic color glazes are achieved by adding metal colorants to the glass enamel to achieve color development during the firing process. Such glaze colors are often single in color and cannot highlight the artistic beauty of the ceramic color glaze itself and the high-temperature firing process. special artistic effects produced in Cobalt carbonate high-temperature purple ceramic glaze effectively overcomes the shortcoming...
