Production Process

Fused Silica Product Description

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

Discover our premium fused silica products:

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 products.

Manufacturing Process

The silica sand is melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder based on customer requirements.
