Fused Silica Product Description



Welcome to Lianyungang Chemsize International Trading Co., Ltd.



Discover our high-quality fused silica products:



Fused Silica Production Process


Fused silica is a 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.



Key Features:



  • High purity silica sand (SiO2 > 99%) sourced locally from Donghai/Xinyi

  • Melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingot

  • Available in fused silica lump, sand, and powder forms



Benefits:



  • Excellent stability for highly cyclical applications

  • Customizable products tailored to customer requirements

  • Perfect for aluminum launders and other refractory applications

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 resulting material is engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour forms. These 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 such as string, plastic, carbon, wood, metal, or other contaminants.

  3. Color dots are not allowed 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.



If you have any questions or inquiries, please feel free to contact us.
