Product Description:
Lianyungang Chemsize International Trading Co., Ltd. specializes in the production of fused silica, a high-purity quartz sand that is melted to form glass. Fused silica offers high volume stability, low volumetric expansion, and exceptional purity, making it ideal for various refractory applications, including aluminum launders.
We meticulously select high-purity silica sand (SiO2>99%) from Donghai/Xinyi as our raw material. Through a process of melting the silica sand at high temperatures (2000-2300 ºC) and subsequent cooling, we produce amorphous silicon dioxide glassy ingots. These ingots are further processed into fused silica lumps, sand, and powder to meet our customers' specific 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 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:
- Must not contain any unfused parts.
- Should be free of foreign materials like strings, plastic lines, carbon, wood, metal, or other contaminants.
- Only conditional black dots are allowed; all other color dots are prohibited.
- Black spot diameter should not exceed 2mm.
- Total black dots quantity should be less than 10 per square meter when opening the big bag.
