White Zirconia Silicate Powder 65% Ceramic Raw Material Zrsio4

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.

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.
