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 source high purity silica sand (SiO2 > 99%) from Donghai/Xinyi for our production process.

Manufacturing Process

The silica sand is melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingots, which are then cooled and processed into fused silica lumps, sand, and powder according to customer requirements.

Lianyungang Chemsize offers a diverse range of fused silica options for various needs. Choose from different mesh sizes, micron ranges, and low iron content for applications like induction furnace lining, investment casting, and more.

Fused Silica Making Process

Fused Silica is produced from high-purity crystal silica sourced from Donghai-Xinyi, China. 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.

 
• Any color dots are prohibited except for conditional black dots.

 
• Black spot diameter should not exceed 2mm.

 
• Total quantity of black dots should be less than 10 per square meter when opening the big bag.
