Fused Silica Product Description
Welcome to Lianyungang Chemsize International Trading Co., Ltd.
Discover our premium fused silica products:
Fused Silica Production Process
Fused silica is 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.
Raw Material
We carefully select high-purity silica sand (SiO2 > 99%) from Donghai/Xinyi as our raw material.
Manufacturing Process
The silica sand is melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingots, which are then cooled. We offer fused silica lumps, sand, and powder tailored to meet customer requirements.
Fused Silica high clear pictures for various applications. Supplier of Epoxy Molding Compound Silica Powder. Precision materials for investment casting and foundry needs.
Fused Silica Package and Delivery: 25kg net plastic woven bags, palletized for shipment.

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 create amorphous Silicon dioxide. The resulting material is engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are specifically designed for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
Fused Silica Sand Appearance and Specifications:
- No unfused parts are allowed.
- No foreign materials such as string, plastic, carbon, wood, metal, or other contaminants are permitted.
- Conditional black dots are acceptable, but 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.
