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 a very useful and versatile material for refractory applications, such as aluminum launders or other highly cyclical applications.
At Lianyungang Chemsize International Trading Co., Ltd., we strictly choose high purity silica sand (SiO2 > 99%) from local Donghai/Xinyi as our raw material. The silica sand is melted at high temperatures (2000-2300 ºC) to form an amorphous silicon dioxide glassy ingot, which is then cooled. We further process the products into fused silica lumps, sand, and powder according to our customers' requirements.
Discover our high-quality fused silica flour, perfect for enhancing refractory properties in various applications. Our specialty silica product is ideal for castables, mortars, investment casting materials, and more. Trust our customized refractory materials for high-temperature applications.
Our Fused Silica Flour is perfect for enhancing refractory properties. Made from high-quality quartz sand, it's ideal for castables, mortars, and investment casting materials. With excellent thermal insulation and heat resistance, it's a must-have for the refractory industry. Order now!
Explore our state-of-the-art fused silica factory and see our rigorous quality control measures. We are Lianyungang Chemsize International Trading Co., Ltd., a leading supplier of high-quality fused silica for enhanced refractory properties. Our products include silica flour, quartz sand, fused silica grit, and more. Trust us for all your industrial refractory needs.
Fused Silica is made of high purity crystal silica from China Donghai-Xinyi by electrically fusing (fusing temperature 1800-2000ºC) to amorphous Silicon dioxide. It is then specially engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour form. These forms are designed for making PV fused silica crucible, thermal ceramic, refractory, EMC investment casting ceramic shell, and more.
