Production Process

Fused Silica Production Process - 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 very useful and versatile material for refractory applications, whether in aluminum launders or other highly cyclical applications.

At Lianyungang Chemsize International Trading Co., Ltd., we strictly choose high purity silica sand (SiO2>99%) from the local Donghai/Xinyi region as our raw material. 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 products into fused silica lump, sand, and powder according to our customer's requirements.

Fused Silica Making Process

Fused Silica is made from high purity crystal silica sourced from China Donghai-Xinyi. It is electrically fused at a temperature of 1800-2000ºC to create amorphous Silicon dioxide. The fused silica is then specially engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour forms. These forms are designed for various applications such as making PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.

Fused Silica Sand Appearance and Specifications:

1. It is forbidden to contain any unfused parts.


2. It is forbidden to have foreign materials, such as string, plastic line, carbon or wooden material, metal, or other outside contaminants.


3. All color dots are forbidden, except for conditional black dots.


4. Black spot diameter larger than 2mm is not acceptable.


5. Total black dots quantity should be less than 10 when opening the big bag, equal to or less than 10 dots per square meter.
