Zirconium silicate
is a non-toxic, odorless white or off-white powder. The raw material is natural high-purity zircon sand concentrate, which is then processed through superfine grinding, iron removal, titanium processing, and surface modification treatment.Zirconium silicate has a high refractive index of 1.93-2.01 and stable chemical performance. It is a high quality and low price opacifier for opacification.
Feature of Zirconium Silicate
zirconium silicate has high refractive index, good chemical stability and high temperature resistance.

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.
