Fused Silica Production Process
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 fused silica a versatile material for refractory applications.
Raw Material
We source high purity silica sand (SiO2 > 99%) from Donghai/Xinyi for our production process.
Manufacturing 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 products into fused silica lumps, sand, and powder based on customer requirements.

Fused Silica Product Description
Fused Silica Making Process
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 engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are ideal for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
Fused Silica Sand Appearance and Specifications:
- No unfused parts are allowed.
- Foreign materials like string, plastic, carbon, wood, metal, or other contaminants are prohibited.
- Only conditional black dots are acceptable.
- Black spot diameter should not exceed 2mm.
- Total black dots quantity should be less than 10 per square meter.
