Fused Silica

Description
We strictly choose 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 a何er 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.
Special Feature
Fused Silica features extremely low coefficient of thermal expansion, consistent chemistry and carefully controlled particle size distribution
Applications
Fused Silica are used in ceramic,refractory,investment casting,EMC,solar crucible,etc.
