Production Process

Fused Silica Production Process

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 an amorphous silicon dioxide glassy ingot, which is then cooled. The ingot is further processed into fused silica lump, sand, and powder based on customer requirements.

Company Information

Fused Silica Product Description

Fused Silica Making Process

Fused Silica is produced from high purity crystal silica sourced from China Donghai-Xinyi. The process involves electrically fusing the silica at temperatures ranging from 1800-2000ºC to create amorphous Silicon dioxide. The resulting 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.

Fused Silica Sand Appearance and Specifications:

• Must not contain any unfused parts.


• Should be free from foreign materials like strings, plastic lines, carbon, wood, metals, or other contaminants.


• Color dots are not allowed except for conditional black dots.


• Black spot diameter should not exceed 2mm.


• Total quantity of black dots should be less than 10 per square meter when opening the big bag.
