Prodcut Name:Fused Silica

Product Description

Fused Silica is a high purity synthetic amorphous silicon dioxide. It is a noncrystalline, colorless material has excellent chemical stability, and has extremely low electrical conductivity. Fused Silica is an excellent raw material for use in investment casting, refractories, foundries, technical ceramics and other applications that require a consistent, high purity product with very low thermal expansion.
