Zirconium Silicate

Product Introduction：
Molecular formula:  ZrSiO
Character: As a chemical compound, zirconium sllicate is a kind of nontoxic tasteless white or grey powder. Its main component is ZrO₂, Index of refraction: 1.93-2.0, Moh's scale: 7-8, Melting point: 2500 ℃, Thermal expanslon: 4.5*10A(-6)(20- 1400 ℃).

Product Highlights:
1. High stability
Our zirconium silicate improves the bonding strength between clay and glaze in stable chemical property, and increase the color and hardness of glaze's surtace.
2 Whitening
We   produce   micro   size   of   zirconium   silicate   to   increase   the   light   reflectior effect which will aprear whiter than those of bigger sizes.
3 Opacification:
It's a cheaper opacifier with high quality that is widespread apply in different types of ceramic productions, such as building ceramics, sanitary ceramics, and daily ceramics etc..

Application:
Zirconium silicate is an excellent opacifier, which is widely used in the production of various building ceramics, sanitary ceramics, daily ceramics and handicraft ceramics, and also widely used in industries such as precision casting, advanced refractory materials, and emulsification glass.
