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 for our products.
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.
Discover our Low Iron Fused Silica Sand Flour for high clarity pictures and various applications. This product offers thermal shock resistance, low thermal expansion, and high fusion ratio.
Fused Silica Package and Delivery: 25kg Net Plastic Woven Bags on Pallets. Ideal for various applications.
Explore our Low Iron Fused Silica Sand Flour for various applications like investment casting, refractory materials, and more. High purity, low iron content, and exceptional thermal properties.
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.
