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 it 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 amorphous silicon dioxide glassy ingots, which are then cooled. The ingots are further processed into fused silica lumps, sand, and powder based on customer requirements.
