Abstract

The invention relates to a high-temperature purple cobalt oxide ceramic glaze and a preparation method thereof, belonging to the ceramic field. The high-temperature purple cobalt oxide ceramic glaze is prepared by the steps of firstly preparing a high-temperature purple cobalt oxide ceramic glaze material, and carrying out glazing and high-temperature sintering, wherein the high-temperature purplecobalt oxide ceramic glaze material contains the following raw materials in percentage by mass: 35%-45% of feldspar powder, 15%-25% of silicon dioxide, 4%-8% of spherical clay, 5%-11% of dolomite, 10%-20% of talcum, 8%-15% of sodium pyroborate, 2%-5% of cobalt oxide and 1%-4% of manganese dioxide. By virtue of long-term adjustment and multiple experiments of a glaze formula, long-term experimentsat -30 DEG C show that the phenomenon that a glaze surface cracks or falls does not appear, and the glaze surface can resist ordinary acid-base corrosion.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a cobalt oxide 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 oxide high-temperature purple ceramic glaze effectively overcomes the lack of single colo...
