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 extremely 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 customer requirements.

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 material is then specially engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are specifically designed for applications like PV fused silica crucible, thermal ceramic, refractory, EMC investment casting ceramic shell, and more.



Fused Silica Sand Appearance and Specifications:



  • Must not contain any unfused parts.

  • Should be free of foreign materials like string, plastic line, carbon, wood, metal, or other contaminants.

  • Only conditional black dots are allowed; all other color dots are forbidden.

  • Black spot diameter should not exceed 2mm.

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