Company name: Lianyungang Chemsize International Trading Co., Ltd.
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 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 according to customer requirements.
Explore investment casting trends with our high-quality fused silica sand. Stay updated on market insights and pricing forecasts.

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.
