Fused silica is high purity quartz sand that has been melted to form glass. Its high volume stability, low volumetric expansion, and high purity make it a versatile material for refractory applications.
We source high purity silica sand (SiO2 > 99%) from Donghai/Xinyi for our production process.
The silica sand is melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingots, which are then cooled. We further process the ingots into fused silica lumps, sand, and powder based on customer requirements.

Explore our High Purity Fused Silica for Investment Casting Refractory, ideal for various applications like induction furnace lining and ceramic welding hot repairs. Benefit from its low iron content and exceptional thermal shock resistance.
Fused Silica is produced from high purity crystal silica sourced from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000ºC to create amorphous Silicon dioxide. The resulting material is then specially processed into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are specifically designed for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
