Fused Silica features an extremely low coefficient of thermal expansion, 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.
The following sizes of Fused Silica are available:
The particle size can be produced according to the customer's special requirements.
For more information, please contact Lianyungang Chemsize International Trading Co., Ltd.
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 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 products into fused silica lumps, sand, and powder according to our customers' requirements.
