Discover our premium fused silica products, meticulously crafted for exceptional performance in refractory applications. Our fused silica is derived from high-purity quartz sand, ensuring unparalleled quality and reliability.
We carefully select high-purity silica sand from Donghai/Xinyi as our raw material. Through a meticulous process of melting at temperatures ranging from 2000-2300 ºC, the silica sand transforms into amorphous silicon dioxide glassy ingot. The resulting fused silica is then processed into lump, sand, and powder variants to meet the specific requirements of our customers.
Choose Lianyungang Chemsize International Trading Co., Ltd. for top-tier fused silica products that excel in aluminum launders and other demanding applications.
