Fused Silica

Product Description: Fused Silica is a high-quality material with exceptional properties that make it ideal for various industrial applications. It is made from fused quartz, resulting in a product with an extremely low coefficient of thermal expansion, consistent chemistry, and a 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 extensive use in industries such as thermal ceramics, refractories, investment casting, EMC, solar crucibles, quartz marbles, and powder coating.

Available Sizes: Fused Silica is available in various 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. We can also produce particle sizes according to customer's special requirements.

About Us: Lianyungang Chemsize International Trading Co., Ltd. is a reputable company specializing in the trading of high-quality materials. We strive to provide our customers with the best products and services.

Production Process

Fused Silica Production Process

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 an extremely useful and versatile material for refractory applications, including aluminum launders and 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 region 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 ingot into fused silica lumps, sand, and powder according to the specific requirements of our customers.
