Fused Silica 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 high purity make it a very useful and versatile material for refractory applications, such as aluminum launders or other highly cyclical applications.
At Lianyungang Chemsize International Trading Co., Ltd., we strictly choose high purity silica sand (SiO2>99%) from local 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. We further process the products into fused silica lump, sand, and powder according to our customers' requirements.

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.
