Production Process

Product Description:

Lianyungang Chemsize International Trading Co., Ltd. specializes in the production of high purity fused silica. Our fused silica is made from locally sourced high purity silica sand (SiO2>99%) from Donghai/Xinyi. Through a meticulous process of melting the silica sand at high temperatures (2000-2300 ºC) and cooling, we create amorphous silicon dioxide glassy ingots that are 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 demanding industrial uses.

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 material is then specially engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are 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 string, plastic, 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.
