Abstract

A method for preparing bismuth zirconate ceramic glaze with photocatalytic function. Quartz, potassium feldspar, albite, borax, Bi2O3, Suzhou soil, and lithium carbonate are mixed together and kept at 1270-1290°C for 20-40 minutes, then taken out and poured. Quench in water to obtain frit; grind the frit to obtain material A; mix material A with Bi2O3, ZrO2 and Suzhou soil to obtain material B; add material B and dispersant to water, stir and mix to prepare glaze Slurry; apply the glaze slurry on the ceramic surface and bake to obtain bismuth zirconate ceramic glaze with photocatalytic function. The enamel produced by the invention has good gloss and stable chemical properties. The present invention uses a firing process to prepare ceramic glaze without coating, so that the prepared functional ceramic glaze is closely combined with the ceramic matrix and is not easy to fall off, and crystallized flowers with special shapes can be quickly formed on the surface of the glaze. The decorative 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.
