Sell Zirconium Silicate

Adopting advanced technology and equipment,Premium grade zirconium silicate is used as opacifier medium for ceramic industries

Usages:

1. Used as opacifier medium for ceramic industries with best quality and cheap cost, widely used for construction ceramic, sanitary ceramic, household ceramic and electric ceramic.

2. Used in the glaze for sanitary ware, tableware and building ceramics.The fine particle size, superior distirbution of grain and the pure chemical composition has ensured the most effective opacifying property for the zirconium silicate with high index of refraction.
