Production Process

Fused Silica Production Process

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

At Lianyungang Chemsize International Trading Co., Ltd., we ensure the highest quality by carefully selecting high purity silica sand (SiO2 > 99%) from the local Donghai/Xinyi area as our raw material. Through a process of melting the silica sand at temperatures between 2000-2300 ºC and subsequent cooling, we transform it into an amorphous silicon dioxide glassy ingot. To meet the specific requirements of our customers, we further process the ingot into fused silica lumps, sand, and powder.

Fused Silica Making Process

Fused Silica Making Process

Fused Silica is made of high purity crystal silica from China Donghai-Xinyi by electrically fusing (fusing temperature 1800-2000ºC) to amorphous Silicon dioxide. It is then specially engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour form. These forms are designed for making PV fused silica crucible, thermal ceramic, refractory, EMC investment casting ceramic shell, and more.

Fused Silica Sand Appearance and Specifications:

• It is forbidden to contain any unfused parts.


• It is forbidden to have foreign material, such as string, plastic line, carbon or wooden material, metal, or other outside contaminants.


• All color dots are forbidden except conditional black dots.


• Black spot diameter larger than 2mm is not acceptable.


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