We strictly choose the high purity silica sand (SiO2>99%) as the raw material. The melted sand become amorphous silicon dioxide glassy ingot after being fused at high temperature (2000 -2300) ℃ and cooling. We further process the products into lump, grain and powder in accordance with customer's requirement.
Fused Silica features extremely low coefficient of thermal expansion, consistent chemistry and carefully controlled particle size distribution.

Fused Silica are used in ceramic,refractory,investment casting,EMC,solar crucible,etc.
