Product Description: Fused Silica is a high-quality material with exceptional properties that make it suitable for various industrial applications. It is made from fused quartz, resulting in an extremely low coefficient of thermal expansion, consistent chemistry, and carefully controlled particle size distribution.
Special Feature: Fused Silica's special feature lies in its exceptional properties, including its low coefficient of thermal expansion, consistent chemistry, and carefully controlled particle size distribution.
Applications: Fused Silica finds applications in various industries, including thermal ceramic, refractory, investment casting, EMC, solar crucible, quartz marble, and powder coating.
Available Sizes: Fused Silica is available in a range of sizes, including 0-1mm, 1-3mm, 3-5mm, 0.2-0.5mm, and 0.1-0.5mm. Other available sizes include -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.
Customization: We can produce Fused Silica particles according to customer's special requirements.

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 in aluminum launders or other highly cyclical applications.
At Lianyungang Chemsize International Trading Co., Ltd., we strictly choose high purity silica sand (SiO2>99%) from the local Donghai/Xinyi area 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.
