Fused Silica Production Process
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, such as aluminum launders.
At Lianyungang Chemsize International Trading Co., Ltd., we carefully select high-purity silica sand (SiO2 > 99%) from 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 to meet our customers' specific requirements.

Lianyungang Chemsize International Trading Co., Ltd. presents Fused Quartz Powder for Refractory Applications. Explore our high purity silica powder for various uses like investment casting and powder coating.
Fused Silica is meticulously crafted from high purity crystal silica sourced from China Donghai-Xinyi. Through an electric fusion process at temperatures ranging from 1800-2000ºC, the silica is transformed into amorphous Silicon dioxide. The resulting product is engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour, tailored for applications like PV fused silica crucible, thermal ceramic, refractory, EMC investment casting ceramic shell, and more.
