Abstract

The invention discloses a preparation method of zirconate bismuth ceramic microcrystal opacifying glaze with a photocatalysis function, which comprises the following steps: quartz, potassium feldspar, soda feldspar, borax, Bi2O3, Suzhou clay and lithium carbonate are poured into water to be quenched to obtain a frit after being compounded and subjected to heat preservation at 1270 to 1290 DEG C; a material A is obtained after the frit is ground; a material B is obtained after the material A, Bi2O3, ZrO2 and Suzhou clay are compounded; the material B and a dispersant is added into water and is glazed onto the surface of ceramics after being stirred uniformly, and sintering is performed to obtain the zirconate bismuth ceramic microcrystal opacifying glaze with the photocatalysis function. According to the preparation method, the ceramic glaze is prepared by a sintering process without the need of coating, so that the prepared functional ceramic glaze is bonded tightly with a ceramic basal body, and is not easy to fall off, a photocatalyst bismuth zirconate generated by the Bi2O3 and the ZrO2 in the sintering process has uniform distribution in the glaze and crystal flowers with special shapes can be formed rapidly on the surface of the glaze, the surface decoration effect is well.

Description

technical field [0001] The invention belongs to the technical field of ceramic materials, and relates to a preparation method of architectural ceramics or daily-use ceramic surface glazes, in particular to a preparation method of bismuth zirconate ceramic microcrystalline opaque glazes with photocatalytic function. Background technique [0002] After the 21st century, with the enhancement of public awareness of environmental protection, people have more and higher requirements for the functions of ceramic materials. Therefore, researchers began to pay attention to some environmentally friendly functional ceramics, including photocatalytic self-cleaning ceramics. Photocatalytic self-cleaning ceramics are functional ceramics that can sterilize, degrade organic pollutants, degrade toxic gases on the surface and keep the ceramic surface clean [Fujishima A, Rao T N, Tryk D A.Titanium Dioxide Photocatalysis[J].J.Photochem. Photobio. C, Phtochem. Rev. 2000, 1-21.]. It differs fro...
