Production Process

Fused Silica Production Process

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

Discover our high-quality fused silica products, meticulously crafted through a precise production process:

Fused Silica Production Process

• High purity quartz sand is melted to form glass


• Offers high volume stability and low volumetric expansion


• High purity makes it ideal for refractory applications

Raw Material

We source our raw material from local Donghai/Xinyi, ensuring high purity silica sand (SiO2 > 99%)

Manufacturing Process

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

Choose Lianyungang Chemsize International Trading Co., Ltd. for top-notch fused silica products tailored to your needs.
