Fused Silica Production Process
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 fused silica a versatile material for refractory applications, such as in aluminum launders or other highly cyclical applications.
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 ingot, which is then processed into fused silica lump, sand, and powder based on customer requirements.
Discover high-quality Fused Silica for industrial applications from Lianyungang Chemsize. Supplier of reliable Fused Quartz in various forms for diverse industrial needs.
Reliable Fused Silica Supplier offering 25kg plastic woven bags on pallets. Ideal for industrial use, including ceramic welding and investment casting.
Explore our Fused Silica Factory and Quality Control images showcasing our reliable industrial-grade products. Choose us as your trusted supplier for high-quality amorphous silicon oxide at affordable prices.
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 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.
