Silica （Quartz）Sand
High purity silica sand (Natural crystal powder)
High purity silica sand is manufactured from natural high quality crystal stone, for its high content of SiO2 and low impurity, it can be used as material for producing optical fiber, fused quartz glass tube rod and for Solar industrial electric arc crucible, fiber communication, lighting and semiconductor industry etc.

Refined silica sand
Refined silica sand is processed from natural 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 abrasives industry etc.
