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, such as in aluminum launders or other highly cyclical applications.

We strictly select high-purity silica sand (SiO2>99%) from Donghai/Xinyi as our raw material. The melted silica sand transforms into amorphous silicon dioxide glassy ingot after being fused at high temperatures (2000-2300 ºC) and cooling. We further process the products into fused silica lump, sand, and powder according to customer requirements.
