Fused silica is a high purity quartz sand that has been melted to form glass. Its high volume stability, low volumetric expansion, and high purity make it an ideal material for refractory applications, such as aluminum launders.
At Lianyungang Chemsize International Trading Co., Ltd., we carefully select 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 processed into fused silica lumps, sand, and powder according to customer specifications.
Discover our Low Thermal Expansion Fused Silica Investment Casting Material for high-quality pictures. Perfect for various applications like induction furnace lining and powder coating fillers.
25kg net Fused Silica Plastic Woven Bag packaging on pallet for delivery by Lianyungang Chemsize International Trading Co., Ltd.
Explore our Low Thermal Expansion Fused Silica Investment Casting Material for superior quality and performance. Ideal for various applications including induction furnace lining, powder coating filler, and more.
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.
