Product Description
Micronized Zirconium Silicate White Zirconium Silicate Powder Zrsio4 for Sanitary Ceramic

Zirconium Silicate Description
Zirconium silicates is non-toxic, odorless, white or off white powder, which is made from high-purity zircon sand concentrate through ultra-thin crushing, iron removal, titanium processing, surface modification etc. It's a kind of high-quality and low-cast opacifier, whitening agent, permeability-reducing agent and stabilizing agent of ceramic glaze.It has good chemical stability, is not easily affected by the firing environment of ceramics, and can significantly improve the glaze bonding performance of ceramics and the hardness of ceramic glazes. Widely used in the production of various architectural ceramics, sanitary ceramics, daily-use ceramics, and first-class ceramic artware.

Applications of Zirconium Silicate
Zirconium silicate is widely used in the production of various architectural ceramics, sanitary ceramics, daily-use ceramics and first-class craft ceramics because of its good chemical stability. It can significantly improve the bonding performance of ceramic glazes and improve the hardness of ceramic glazes. . Zirconium silicate is further used in the production of color picture tubes, emulsified glass and enamel glaze in the glass industry. Zirconium silicate has a high melting point: 2500 degrees Celsius, so it is also widely used in refractory materials, glass furnace zirconium ramming materials, castables, and spray coatings.
