Company Name: Lianyungang Chemsize International Trading Co., Ltd.
At Lianyungang Chemsize, we specialize in the production of high-purity fused silica for various refractory applications. Our fused silica is made from locally sourced high-purity silica sand with a SiO2 content of over 99%. Through a meticulous process of melting the silica sand at temperatures ranging from 2000-2300 ºC, we create amorphous silicon dioxide glassy ingots that exhibit exceptional stability and low volumetric expansion.
Our fused silica products, available in lump, sand, and powder forms, are tailored to meet the specific requirements of our customers. Whether used in aluminum launders or other demanding applications, our fused silica offers unparalleled purity and versatility.

25kg Net Fused Silica Plastic Woven Bags on Pallet for Delivery by Lianyungang Chemsize International Trading Co., Ltd.
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 resulting material is engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are ideal for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
