Production Process

Product Description: Fused Silica

Fused silica is a high-purity quartz sand that has been melted to form glass. Its high volume stability, low volumetric expansion, and exceptional purity make it an incredibly versatile material for refractory applications, such as in aluminum launders and other high-cyclical uses.

At Lianyungang Chemsize International Trading Co., Ltd., we meticulously select high-purity silica sand (SiO2 > 99%) from Donghai/Xinyi as our raw material. This silica sand is melted at temperatures ranging from 2000-2300 ºC to create an amorphous silicon dioxide glassy ingot, which is then cooled and processed into fused silica lump, sand, and powder based on our customers' specific requirements.

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 resulting material is engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are ideal 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. No foreign materials like strings, plastic lines, carbon, wood, metal, or other contaminants are permitted.


3. Only conditional black dots are acceptable; all other color dots are prohibited.


4. Black spot diameter should not exceed 2mm.


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