Production Process

Product Description:

Lianyungang Chemsize International Trading Co., Ltd. specializes in the production of high purity fused silica. Our fused silica, made from locally sourced high purity silica sand (SiO2>99%) from Donghai/Xinyi, is ideal for refractory applications due to its high volume stability, low volumetric expansion, and exceptional purity. The silica sand is melted at temperatures ranging from 2000-2300 ºC to form amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder according to customer specifications.

Fused Silica Product Description

Fused Silica Making Process

Fused Silica is produced from high purity crystal silica sourced from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000ºC to create amorphous Silicon dioxide. The material is then specially processed 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. Must not contain any unfused parts.


2. Should be free of foreign materials like strings, plastic lines, carbon, wood, metal, or other contaminants.


3. Any color dots are prohibited except for conditional black dots.


4. Black spot diameter should not exceed 2mm.


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