Fused Silica Production Process

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 temperature (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.

Fused Silica Special Feature:

Fused Silica features an extremely low coefficient of thermal expansion, consistent chemistry, and a carefully controlled particle size distribution.

Fused Silica Applications:

Fused Silica is used in various industries, including thermal ceramic, refractory, investment casting, EMC, solar crucible, quartz marble, and powder coating.

Fused Silica Available Sizes:

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, 1250mesh, etc. The particle size can be produced according to the customer's special requirements.
