The zirconium silicate is non-toxic, tasteless, white or offwhite powder, made of high-purity zircon sand concentrates by process of ultra-thin crushing, iron removal, titanium processing, surface modification, etc., and is a good-quality and cheap opacifier, whitening agent, permeability-reducing agent and stabilizing agent of ceramic glaze.
The zirconium silicate has good chemical stability, is insusceptible to ceramics firing atmosphere, can obviously improve the glaze-body bonding performance of ceramics and the hardness of ceramic glaze, and is widely used in the production of various building ceramics, sanitary ceramics, domestic ceramics, first-class ceramic artware, etc. Meanwhile, the zirconium silicate is further applied to color picture tubes in television industry, emulsification glass in glass industry and production of enamel glaze materials.
