Fused Silica Production Process



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.



At Lianyungang Chemsize International Trading Co., Ltd., we source high purity silica sand (SiO2 > 99%) from Donghai/Xinyi as our raw material. The silica sand is melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder according to customer requirements.

Fused Silica Grains for High-Temperature Furnaces


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 form amorphous Silicon dioxide. The 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:



  1. Must not contain any unfused parts.

  2. Should be free of foreign materials like strings, plastic lines, carbon, wood, metal, or other contaminants.

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

  4. Black spot diameter should not exceed 2mm.

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