Production Process

Fused Silica Production Process

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

At Lianyungang Chemsize, we specialize in the production of high purity fused silica using locally sourced silica sand from Donghai/Xinyi. Our fused silica is ideal for refractory applications due to its high volume stability, low volumetric expansion, and exceptional purity (SiO2>99%).

Key Features:

• High purity quartz sand melted to form glass


• Excellent volume stability


• Low volumetric expansion


• Versatile material for various applications

Production Process:

The silica sand is melted at temperatures ranging from 2000-2300 ºC to form amorphous silicon dioxide glassy ingots. These ingots are then processed into fused silica lumps, sand, and powder according to customer specifications.

Choose Lianyungang Chemsize for top-quality fused silica products tailored to your needs.

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 form amorphous Silicon dioxide. The resulting material is then specially processed 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 string, plastic, 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 quantity should be less than 10 per square meter when opening the big bag.
