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, such as aluminum launders.

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.

Company Information

Company Name: Lianyungang Chemsize International Trading Co., Ltd.

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 form amorphous Silicon dioxide. The material is then specially engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour forms. These 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 of foreign materials such as strings, plastic lines, carbon, wood, metal, or other contaminants.


• Any color dots are prohibited 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.
