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 it an ideal 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 and durability


• Perfect for aluminum launders and other high-cyclical applications


• Customizable products tailored to meet customer requirements

Choose Lianyungang Chemsize for premium fused silica products that meet your specific 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 form amorphous Silicon dioxide. The material is then engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are specifically designed for creating 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.


• 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.
