Abstract

The invention relates to a preparation method of bismuth zirconate microcrystal ceramic glaze with a photocatalytic function. The preparation method includes: blending quartz, potassium feldspar, albite, borax, Bi2O3, Suzhou kaolin and lithium carbonate according to the mass ratio, performing heat preservation at 1270-1290 DEG C for 20-40 minutes, taking out, pouring into water for quenching, and grinding to obtain a material A; blending the material A, the Bi2O3, ZrO2 and the Suzhou kaolin according to the mass ratio to obtain a material B; adding the material B and a dispersing agent into water, and evenly stirring to prepare glaze slip; glazing the surface of ceramic with the glaze slip, and sintering to obtain the bismuth zirconate microcrystal ceramic glaze with the photocatalytic function. The preparation method has the advantages that the ceramic glaze is prepared by the sintering process, coating is not needed, the prepared functional glaze can be tightly combined with a ceramic matrix, the photocatalyst generated during the sintering of the Bi2O3 and the ZrO2 is evenly distributed in the glaze, and the 'rainbow effect' which affects glaze attractiveness is not generated.

Description

technical field [0001] The invention belongs to the technical field of ceramic glazes, in particular to a method for preparing bismuth zirconate microcrystalline ceramic glazes with photocatalytic function, which can be applied to the surface of building ceramics or daily-use ceramics. Background technique [0002] Building sanitary ceramics and daily-use ceramics are materials that are widely used in people's daily life and can be seen everywhere. It is understood that the output of my country's architectural ceramics and daily-use ceramics has ranked first in the world for more than ten consecutive years. However, in recent years, with the improvement of people's living standards, the health requirements and environmental protection requirements for ceramic products have also gradually increased. Ordinary ceramics can no longer meet people's needs, and new ceramics with specific functions have gradually entered people's field of vision. The difference between this type o...
