Discover our top-quality fused silica products, meticulously crafted to meet your refractory needs.
Fused silica, derived from high purity quartz sand, is melted to create a glass with exceptional properties. Its high volume stability, low volumetric expansion, and purity make it ideal for various refractory applications.
We source our raw material from Donghai/Xinyi, ensuring a purity level of SiO2>99% for superior quality.
The silica sand undergoes fusion at temperatures of 2000-2300 ºC, transforming into amorphous silicon dioxide glassy ingot. Our products are further processed into fused silica lump, sand, and powder to meet your specific requirements.

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 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 manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
