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, such as aluminum launders.
At Lianyungang Chemsize International Trading Co., Ltd., we carefully select 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 based on customer requirements.
Discover our Low Iron Fused Silica Sand Flour, ideal for various applications like artificial quartz marble and investment casting. With a fusion ratio and thermal shock resistance, it offers high purity and low iron content.
Our Low Iron Fused Silica Sand Flour comes in a 25kg plastic woven bag, palletized for secure delivery. Perfect for various industrial applications.
Explore our Low Iron Fused Silica Sand Flour, ideal for various applications like investment casting, refractory shapes, and more. With a fusion ratio, high purity, and low iron content, this silica powder ensures exceptional quality.
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. 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.
