Company Name: Lianyungang Chemsize International Trading Co., Ltd.
Fused Silica is a high-quality material with an extremely low coefficient of thermal expansion. It offers consistent chemistry and a carefully controlled particle size distribution.
Fused Silica is widely used in various industries, including thermal ceramic, refractory, investment casting, EMC, solar crucible, quartz marble, and powder coating.
Fused Silica is available in the following sizes:
The particle size can also be produced according to the 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 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 lump, sand, and powder according to our customers' requirements.
