Production Process

Fused Silica Production Process

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

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 it an incredibly useful material for refractory applications, such as aluminum launders.

At Lianyungang Chemsize, we carefully select high-purity silica sand (SiO2 > 99%) from local sources in Donghai/Xinyi as our raw material. This silica sand is melted at high temperatures (2000-2300 ºC) to create an amorphous silicon dioxide glassy ingot, which is then processed into fused silica lump, sand, and powder based on our customers' needs.

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 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. Must not contain any unfused parts.


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


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


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.
