Company name: Lianyungang Chemsize International Trading Co., Ltd.
Product Description:
At Lianyungang Chemsize International Trading Co., Ltd., we specialize in the production of high-purity fused silica. Our fused silica is derived from locally sourced silica sand with a purity of SiO2>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 diverse needs of refractory applications. Whether used in aluminum launders or other high-cyclical environments, our fused silica stands out for its high purity and versatility.
Discover our top-grade Superior Fused Silica Sand for resin filler production. High clarity pictures available for this premium quartz sand. Trust Lianyungang Chemsize International Trading Co., Ltd. for innovative fused silica solutions.
Our Superior Fused Silica Sand comes in 25kg plastic woven bags, securely placed on pallets for delivery. Trust Lianyungang Chemsize for top-grade silica products.
Explore our top-grade silica sand for investment casting and castables. Our premium quartz sand offers high purity and durability for innovative solutions.
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 material is then specially engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are designed for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
