Production Process

Fused Silica Product Description

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

Discover our premium fused silica products, meticulously crafted to meet the highest standards of quality and performance.

Product Features:

• High purity quartz sand (SiO2 > 99%) sourced locally from Donghai/Xinyi


• Exceptional high volume stability and low volumetric expansion


• Versatile material ideal for refractory applications

Production Process:

Our fused silica is produced by melting high purity silica sand at temperatures ranging from 2000-2300 ºC, resulting in an amorphous silicon dioxide glassy ingot. The ingot is then processed into fused silica lump, sand, and powder to meet the specific requirements of our customers.

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 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.
