Abstract

The invention discloses a preparation method of zirconate yttrium ceramic microcrystal opacification glaze with a photocatalysis function. The method comprises the steps that quartz, potassium feldspar, albite, borax, Y2O3, Suzhou clay and lithium carbonate are subjected to batching and then subjected to heat preservation for 20 min to 40 min at the temperature of 1,270 DEG C to 1,290 DEG C, the materials are taken out to be poured into water to be quenched, frit is prepared, and the frit is ground to obtain a material A; the material A, Y2O3, ZrO2 and the Suzhou clay are subjected to batching and then ground to obtain a material B; the material B and a dispersing agent are added into water, and the materials are stirred and mixed to be uniform to obtain glaze slurry; the glaze slurry is glazed on the ceramic surface, firing is conducted through roller kiln oxidizing flame after drying is conducted, and then the Y2ZrO5 microcrystal ceramic glaze with the photocatalysis function is obtained. According to the method, the ceramic glaze is prepared by adopting a firing technology, film coating is not needed, and therefore the prepared functional ceramic glaze is closely bonded with a ceramic base body; a photocatalyst zirconate yttrium generated in the firing process of Y2O3 and ZrO2 is uniformly distributed in the glaze, and the condition that a rainbow effect is generated to influence the glaze attractiveness cannot occur.

Description

technical field [0001] The invention belongs to the technical field of ceramic materials, and in particular relates to a preparation method of yttrium zirconate ceramic microcrystalline opaque glaze with photocatalytic function. Background technique [0002] With the progress of society and the improvement of public living standards, the public's awareness of environmental protection has gradually increased, and they have gradually realized that the home environment and the cleaning and purification of outdoor air are very important [Wang Qianghong. Self-cleaning nano-TiO 2 Preparation and Properties of Thin Film Ceramics [M]. Shanghai: South China University of Technology, 2012:9-12.]. Ceramic products, including daily-use ceramics and architectural ceramics, exist in all aspects of people's lives and are closely related to people's lives. Utilizing the wide usability of ceramic products and endowing them with certain self-cleaning properties, they become functional cerami...
