Fused Silica Production Process
Fused Silica Production Process
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.
Raw Material
We source high purity silica sand (SiO2 > 99%) from Donghai/Xinyi for our production process.
Manufacturing 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.
