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 create amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder based on customer requirements.
Discover high-quality Ultra-Fine Silica Grains for Precision Casting by Lianyungang Chemsize International Trading Co., Ltd. Perfect for investment casting and refractory applications.
Our Ultra-Fine Silica Grains for Precision Casting come in 25kg plastic woven bags, palletized for easy delivery. Trust Lianyungang Chemsize for high-quality fused silica products.

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 transforms into amorphous Silicon dioxide. Our Fused Silica is engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour, tailored for creating PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
