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 carefully select 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 based on customer requirements.

Fused Silica Product Description



Welcome to Lianyungang Chemsize International Trading Co., Ltd.



Fused Silica Making Process


Fused Silica is produced using high purity crystal silica from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000ºC to create amorphous Silicon dioxide. The material is then specially engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour forms. These are designed for various applications such as PV fused silica crucible, thermal ceramic, refractory, EMC investment casting ceramic shell, and more.



Fused Silica Sand Appearance and Specifications:



  • Must not contain any unfused parts.

  • Should be free of foreign materials like string, plastic line, 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.
