Fused Silica, offered by Lianyungang Chemsize International Trading Co., Ltd., is a high-quality material with exceptional properties that make it ideal for various industrial applications.
Fused Silica finds extensive use in industries such as thermal ceramic, refractory, investment casting, EMC, solar crucible, quartz marble, and powder coating.
We can also produce particle sizes according to the specific requirements of our customers.
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 dust-free fused silica sand for investment casting. Perfect for casting applications, our refined fused silica flour offers premium grains and fine particles. Ideal for investment casting raw materials.
