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 strictly choose high purity silica sand (SiO2 > 99%) from 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 ingot, which is then cooled. The products are further processed into fused silica lump, sand, and powder based on customer requirements.

Fused Silica Product Description

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

Fused Silica Making Process

Fused Silica is created using high purity crystal silica from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000ºC to form amorphous Silicon dioxide. Our Fused Silica is engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour forms. These are specifically designed for making 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 not have any foreign materials like string, plastic, carbon, wood, metal, or other contaminants.


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


• Black spot diameter must not exceed 2mm.


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