Discover our high-quality fused silica products, meticulously crafted for refractory applications.
Fused silica is a high-purity quartz sand that undergoes a meticulous melting process to form glass. Its high volume stability, low volumetric expansion, and exceptional purity make it a versatile material for various applications.
We source our high-purity silica sand (SiO2 > 99%) locally from Donghai/Xinyi. The sand is melted at temperatures ranging from 2000-2300 ºC to create amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder based on customer specifications.
Discover our High Purity Fused Quartz Sand Grains for high-quality fused silica applications. Low iron content, high thermal shock resistance, and more.
High Purity Fused Quartz Sand Grains in 25kg plastic woven bags on pallets for secure delivery. Ideal for various applications like investment casting, refractories, and powder coating.
Discover our top-quality fused silica powder with low iron content, ideal for various applications like ceramic welding, investment casting, and refractory materials.
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 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.
