Production Process

Product Description:

Lianyungang Chemsize International Trading Co., Ltd. specializes in the production of high purity fused silica. Our fused silica is derived from locally sourced silica sand with a purity of SiO2>99%. Through a meticulous process of melting the silica sand at temperatures ranging from 2000-2300 ºC, we create amorphous silicon dioxide glassy ingots that are then further processed into fused silica lumps, sand, and powder to meet our customers' specific requirements.

Fused silica offers high volume stability, low volumetric expansion, and exceptional purity, making it an ideal material for refractory applications such as aluminum launders and other high-cyclical uses. Trust Chemsize International Trading Co., Ltd. for top-quality fused silica products that meet your exacting standards.

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 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 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 like strings, plastic lines, carbon, wood, metal, or other contaminants.


• Any color dots are not allowed except for conditional black dots.


• Black spot diameter should not exceed 2mm.


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