Production Process

Product Description: Fused Silica

Fused silica is a high-purity quartz sand that has been melted to form glass. Its high volume stability, low volumetric expansion, and high purity make it an incredibly useful and versatile material for refractory applications, such as in aluminum launders or other highly cyclical applications.

At Lianyungang Chemsize International Trading Co., Ltd., we carefully select high-purity silica sand (SiO2 > 99%) from local sources in Donghai/Xinyi as our raw material. The silica sand is melted at high temperatures (2000-2300 ºC) to form an amorphous silicon dioxide glassy ingot, which is then cooled and processed into fused silica lump, sand, and powder according to our customers' specific requirements.

Fused Silica Product Description

Fused Silica Making Process

Fused Silica is produced from high purity crystal silica from China Donghai-Xinyi through electric fusion at temperatures ranging from 1800-2000ºC. It is then specially engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour for applications like PV fused silica crucible, thermal ceramic, refractory, EMC investment casting ceramic shell, etc.

Fused Silica Sand Appearance and Specifications:

• Must not contain any unfused parts


• Should not have foreign materials like string, plastic line, carbon, wood, metal, or other contaminants


• Only conditional black dots are allowed, no other color dots


• Black spot diameter should not exceed 2mm


• Total black dots quantity should be less than 10 per square meter
