Production Process

Fused Silica Product Description

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

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 aluminum launders.

Raw Material

We strictly select high-purity silica sand (SiO2 > 99%) from local Donghai/Xinyi as our raw material.

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 according to customer requirements.

Fused Silica Product Description

Fused Silica Making Process

Fused Silica is produced using high purity crystal silica from China Donghai-Xinyi. It is electrically fused at temperatures between 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:

• 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 should not exceed 2mm.


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