Fused silica is a high purity quartz sand that has been melted to form glass. Its high volume stability, low volumetric expansion, and high purity make fused silica 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 and processed into fused silica lumps, sand, and powder according to customer specifications.

Fused Silica is produced using high purity crystal silica from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000ºC to create amorphous Silicon dioxide. The material is then engineered 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.
