Abstract

The invention relates to a sodium pyroborate iron black crystalline glaze and a preparation method thereof, and belongs to the technical field of ceramics. The sodium pyroborate iron black crystalline glaze is prepared from the following raw material components in percentage by mass: 35.5 to 38.5 % of sodium pyroborate, 21.5 to 25.5% of potassium feldspar powder, 14.5 to 16.5% of silicon dioxide, 6.6 to 7.6% of lithium carbonate and 11.9 to 21.9% of ferric oxide; the sodium pyroborate iron black crystalline glaze can also be prepared from 1.9 to 2.5% of manganese dioxide and 1 to 1.5% of cobalt oxide. The sodium pyroborate iron black crystalline glaze has the advantages that the particular ceramic glaze art effect is realized, and the silver metal bright spot texture is formed on a black ceramic glaze surface; by adding the sodium pyroborate into the sodium pyroborate iron black crystalline glaze, the required amount of a melting agent is effectively reduced, and the amount of raw materials in the components is reduced; air bubbles on the glaze surface are also prevented by the sodium pyroborate; after long-time experiment at the temperature of minus 30 DEG C, the crack or falling of the glaze surface is avoided, and the corrosion by common acid and alkaline is resisted.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a sodium pyroborate iron black crystalline 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 Sodium pyroborate iron black crystalline glaze effectively overcomes the deficiencies of ceramic gla...
