Description

PROCESS OF PRODUCTION AND CHARACTERISTIC

Fused Quartz is made from high purity silica, using unique fusion technology to ensure the highest quality. Our Fused Quartz is over 99% amorphous and has an extremely low coefficient of thermal expansion and high resistance to thermal shock. Fused Quartz is inert, has excellent chemical stability, and has extremely low electrical conductivity.

 

APPLICATIONS

Fused Quartz 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.
