Production Process

Fused Silica Production Process

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

Our company specializes in the production of high purity fused silica, a versatile material ideal for refractory applications. Fused silica is created by melting high purity quartz sand at temperatures between 2000-2300 ºC, resulting in a stable, low expansion, and highly pure glass material.

We source our raw materials from local Donghai/Xinyi, ensuring a silica sand purity of over 99%. The melted silica sand is transformed into amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder based on customer specifications.

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

Fused Silica Making Process

Fused Silica is produced using high purity crystal silica from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000ºC to create amorphous Silicon dioxide. The resulting material is then engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are specifically designed for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.

Fused Silica Sand Appearance and Specifications:

1. No unfused parts are allowed.


2. Foreign materials like strings, plastic lines, carbon, wood, metal, or other contaminants are strictly prohibited.


3. Except for conditional black dots, all other color dots are not permitted.


4. Black spot diameter should not exceed 2mm.


5. The total quantity of black dots should be less than 10 per square meter when opening the big bag.
