Fused silica is a high-purity quartz sand that has been melted to form glass. Its high volume stability, low volumetric expansion, and high purity make it an ideal material for refractory applications, such as aluminum launders.
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 temperatures ranging from 2000-2300 ºC to form amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder based on customer requirements.
Discover our High Thermal Shock Resistance Fused Quartz Grains for clear and durable pictures. Perfect for various applications in industries like glassmaking, ceramics, and more.
Fused Silica Package and Delivery: 25kg Net Plastic Woven Bags on Pallets for easy handling and transportation.
Explore our premium fused silica sand for various applications. High purity and durability make it ideal for glassmaking, ceramics, refractories, and more.
Fused Silica is produced using high purity crystal silica from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000ºC to create amorphous Silicon dioxide. Our Fused Silica is specially engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour forms. These are designed for various applications such as PV fused silica crucible, thermal ceramic, refractory, EMC investment casting ceramic shell, and more.
