Production Process

Fused Silica Product Description

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

Fused Silica Production Process

Fused silica is a 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 strictly choose high purity silica sand (SiO2 > 99%) from local Donghai/Xinyi as our raw material.

Manufacturing Process

The silica sand is melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingots, which are then cooled. We further process the products into fused silica lumps, sand, and powder according to customer requirements.

Benefits:

• High purity silica sand used


• Amorphous silicon dioxide glassy ingots produced


• Versatile material for refractory applications
