Fused Silica Production Process
Welcome to Lianyungang Chemsize International Trading Co., Ltd.
Discover our high-quality fused silica products:
Fused Silica Features:
- High purity quartz sand
- High volume stability
- Low volumetric expansion
- Excellent purity (SiO2 > 99%)
Production Process:
We carefully select high purity silica sand from Donghai/Xinyi. The sand is melted at 2000-2300 ºC to form amorphous silicon dioxide glassy ingot, which is then processed into fused silica lump, sand, and powder based on customer requirements.
Applications:
Our fused silica is ideal for refractory applications, including aluminum launders and other high-cyclical uses.

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 then specially processed 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.
- Except for conditional black dots, all other color dots are prohibited.
- Black spot diameter should not exceed 2mm.
- Total black dots quantity should be less than 10 per big bag or less than 10 dots per square meter.
