Production Process

Fused Silica Production Process

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, such as in aluminum launders.

At Lianyungang Chemsize International Trading Co., Ltd., we carefully select high-purity silica sand (SiO2 > 99%) from Donghai/Xinyi as our raw material. The silica sand is melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, 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 material is then specially processed into lumps, cullet, ingots, sand, grain, granular, and powder flour forms. These are tailored 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 like strings, plastic lines, carbon, wood, metal, or other contaminants.


• Only conditional black dots are allowed; all other color dots are prohibited.


• Black spot diameter must not exceed 2mm.


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