Company name: Lianyungang Chemsize International Trading Co., Ltd.
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.
At Lianyungang Chemsize International Trading Co., Ltd., we source 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.
Discover our Fused Silica Grains for High-Temperature Furnaces, ideal for extreme heat applications. Trust Lianyungang Chemsize for quality and reliability.
Fused Silica Grains for High-Temperature Furnaces in 25kg plastic woven bags on pallets. Supplier of high temp silica sand for industrial furnaces.
Explore our quality fused silica grains perfect for high-temp applications. Trust our expertise as a leading supplier in the industry.
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 specially processed 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.
