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, such as aluminum launders.
We source high-purity silica sand (SiO2 > 99%) from local Donghai/Xinyi for our production process.
The silica sand is melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingots, which are then cooled. We further process the ingots into fused silica lumps, sand, and powder based on customer requirements.

Fused Silica Package and Delivery: 25kg Net Plastic Woven Bags on Pallets for easy handling and transportation.

Product Name: Fused Quartz Sand with Low Radiation Emissions
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 create amorphous Silicon dioxide. The material is then specially processed 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.
