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 ingot, which is then processed into fused silica lump, sand, and powder according to customer requirements.
Discover our Low Iron Content Fused Silica Grains for high clarity pictures. Perfect for optical applications, our premium quartz sand ensures exceptional quality.
Our Low Iron Content Fused Silica Grains are packaged in 25kg plastic woven bags and placed on pallets for delivery. Ideal for various applications.
Explore our Low Iron Fused Silica Grains for top-quality quartz sand with minimal impurities. Tailored to meet your unique needs.
Fused Silica is crafted from high-purity crystal silica sourced from China Donghai-Xinyi. Through electrical fusion at temperatures ranging from 1800-2000ºC, it transforms into amorphous Silicon dioxide. Our Fused Silica is meticulously engineered into various forms like lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are tailored for creating PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
