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 it an ideal material for refractory applications.

Key Features:

• High purity silica sand (SiO2 > 99%) sourced locally


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


• Available in fused silica lump, sand, and powder

Benefits:

• Excellent stability for highly cyclical applications


• Versatile material for various refractory applications


• Customizable products to meet customer requirements

Lianyungang Chemsize offers high-quality silica quartz sand for foundry work. Our products include fused silica, silica powder, and refractory materials. Explore our selection for your industrial needs.

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 various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are 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 not have any foreign materials like string, plastic, 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.
