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.
We strictly choose high purity silica sand (SiO2 > 99%) from local 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 cooled. We further process the products into fused silica lumps, sand, and powder according to customer requirements.

25kg net Fused Silica Plastic Woven Bag, palletized for delivery. Ideal for Thermal Barrier Coatings.
Explore our Fused Silica Powder for Thermal Barrier Coatings, ideal for high-temperature insulation and heat-resistant coatings. Perfect for various industrial applications.
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 various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are tailored for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
