Company name: Lianyungang Chemsize International Trading Co., Ltd.
Fused silica is 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.
We source high purity silica sand (SiO2 > 99%) from Donghai/Xinyi for our production process.
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 lump, sand, and powder based on customer requirements.
