Abstract

The invention discloses a preparation method of bismuth zirconate microcrystalline ceramic glaze with a photocatalysis function. The preparation method comprises the following steps: blending quartz, potassium feldspar, albite, borax, Bi2O3, Suzhou soil and lithium carbonate; preserving heat at 1,270-1,290 DEG C for 20-40min; taking out and pouring into water for quenching to obtain a frit; grinding the frit to obtain a material A; blending the material A with Bi2O3, ZrO2 and Suzhou soil to obtain a material B; adding the material B and a dispersing agent into water, stirring and uniformly mixing to obtain glaze slip; glazing the ceramic surface with the glaze slip; and firing to obtain a bismuth zirconate ceramic glaze with a photocatalysis function. The glaze prepared According to the invention has good gloss and stable chemical property. According to the invention, the ceramic glaze is prepared by adopting a firing technology, coating is not needed, and thus the prepared functional ceramic glaze is tightly combined with a ceramic base and does not fall off easily; and moreover, crystal flowers of special morphology can be quickly formed on the glaze surface, and the surface decoration effect is good.

Description

technical field [0001] The invention belongs to the technical field of ceramic glazes. Specifically relates to a preparation method of bismuth zirconate microcrystalline ceramic glaze with photocatalytic function. Background technique [0002] Photocatalytic technology began in 1972. Japanese scholars Fujishima and Honda discovered that hydrogen can be produced by photocatalytically decomposing water on semiconductor electrodes [Fujishima A., Honda K. Photocatalysis-decomposition of water at the surface of an irradiated semiconductor[J].Nature, 1972,238(5385):37-38.], this discovery has aroused great attention of scientific and technological workers to photocatalysis. With the increasingly prominent energy and environmental issues, photocatalytic technology has received extensive attention and achieved rapid development. Photocatalytic materials have potential applications in degradation of organic pollutants, air purification, antibacterial and self-cleaning. [0003] Si...
