Top Quality Industrial Grade Zirconium Silicate for Ceramic and Glass
Introduction of Zirconium silicate
Zirconium silicate is a non-toxic, odorless white or off-white powder. It has a high refractive index of 1.93-2.01 and stable chemical performance, so it is widely used in the production of various building ceramics, sanitary ceramics, daily ceramics and first-class handicraft ceramics.
Application of Zirconium silicate
1.Used as an excellent opacifying agent in ceramics, opalescent glazes, paint intensifiers, etc;
2.Used as a raw material for the special glass and porcelain, and a filler for special rubber-reinforced resin;
3.Used in the production of high-grade ceramic glazes, high-grade refractory fibers, TV display screens and other production
fields;
