Silica Sand
1.Introduction
High Purity Silica Sand is processed from the quality silica stone, for its high content of SiO2 and low impurity. It can be used as material for producing optical glass, refractory, metallurgy, ceramic, foundry and abrasive etc.
2.Applications:
1.)Widely used for producing optical glass
2.)Refractory material
3.)Metallurgy, ceramic, foundry and abrasives etc
