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 fused silica a 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 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 processed into fused silica lump, sand, and powder based on customer requirements.
Discover our Superior Fused Quartz Sand for Foundry Needs, offering high purity and quality at an affordable price. Get premium quartz powder from the best supplier in the industry.
Our Fused Silica is packaged in 25kg plastic woven bags and placed on pallets for delivery, ensuring safe transportation.

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 making 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 not have any 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.
