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 fused silica a versatile material for refractory applications, such as aluminum launders and 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 a high temperature of 2000-2300 ºC, resulting in an amorphous silicon dioxide glassy ingot. After cooling, we further process the ingot into fused silica lumps, sand, and powder according to our customers' requirements.
