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 amorphous silicon dioxide glassy ingot, which is then cooled and processed into fused silica lump, sand, and powder according to 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 specifically designed for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.

Fused Silica Sand Appearance and Specifications:

1. No unfused parts are allowed.


2. No foreign materials like strings, plastic lines, carbon, wood, metal, or other contaminants are permitted.


3. Only conditional black dots are acceptable; all other color dots are prohibited.


4. Black spot diameter should not exceed 2mm.


5. Total black dots quantity should be less than 10 per square meter when opening a big bag.
