We strictly choosed the high purity silica sand (SiO2>99%) in local Donghai county (hometown of Crystal) as our raw material. The melted sand become amorphous silicon dioxide glassy ingot after been fused at high temperature(2000-2300 ºC),and cooling. We further process the products into lump,grain and powder in accordance with customer's requirements.
Special Feature:
Fused Silica features extremely low coefficient of thermal expansion,consistent chemistry and carefully controlled particle size distribution.
