Product Description: Fused Silica is a high-quality material with exceptional properties, making it ideal for various industrial applications. It is produced by carefully controlling the particle size distribution and maintaining a consistent chemistry. With an extremely low coefficient of thermal expansion, Fused Silica offers excellent thermal stability.
Applications: Fused Silica finds extensive use in industries such as thermal ceramic, refractory, investment casting, EMC, solar crucible, quartz marble, and powder coating. Its versatility makes it suitable for a wide range of applications.
Available Sizes: We offer Fused Silica in various sizes to meet different requirements. The available sizes include 0-1mm, 1-3mm, 3-5mm, 0.2-0.5mm, 0.1-0.5mm, -10mesh, 10-20mesh, 30-50mesh, 50-100mesh, -100mesh, -150mesh, -270mesh, 30-60mesh, 60-120mesh, 40-70mesh, 70-140mesh, 100-200mesh, 120F, 200mesh, 325mesh, 400mesh, 600mesh, 800mesh, and 1250mesh. We can also produce particle sizes according to customer's special requirements.
Company Information: This product is offered by Lianyungang Chemsize International Trading Co., Ltd., a trusted supplier in the industry.
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 customer's requirements.
Investment Casting Fused Silica Powder - Our high-quality fused silica powder is perfect for investment casting applications. With unmatched quality and a range of size options, our product is the top choice for investment casting professionals. Trust us as your reliable supplier of fused silica powder.
Fused Silica is made of high purity crystal silica from China Donghai-Xinyi by electrically fusing (fusing temperature 1800-2000ºC) to amorphous Silicon dioxide, then is specially engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour form designed for making PV fused silica crucible, thermal ceramic, refractory, EMC investment casting ceramic shell, etc.
