High Pure High Temperature Castable Refractory Raw Material Foundries Ceramics Supply
Fused Silica
Process Of Production And Characteristic
Fused Silica is made from high purity silica, using unique fusion technology to ensure the highest quality. Our Fused Silica is over 99% amorphous and has an extremely low coefficient of thermal expansion and high resistance to thermal shock. Fused Silica is inert, has excellent chemical stability, and has extremely low electrical conductivity.
Applications:
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.
