Production Process

Product Description:

Lianyungang Chemsize International Trading Co., Ltd. specializes in the production of high-purity fused silica, a versatile material ideal for refractory applications. Our fused silica is made from locally sourced high-purity silica sand (SiO2>99%) from Donghai/Xinyi. Through a meticulous process of melting the silica sand at temperatures between 2000-2300 ºC, we create amorphous silicon dioxide glassy ingots that are further processed into fused silica lumps, sand, and powder to meet our customers' specific needs.

Key Features:

• High purity quartz sand melted to form glass


• High volume stability and low volumetric expansion


• Ideal for aluminum launders and other cyclical applications

Benefits:

• Ensures high-quality performance in refractory applications


• Customizable products tailored to customer requirements


• Reliable sourcing of raw materials for consistent quality

Fused Silica Product Description

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 material is then specially engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are designed for applications like PV fused silica crucible, thermal ceramic, refractory, EMC investment casting ceramic shell, and more.

Fused Silica Sand Appearance and Specifications:

• Must not contain any unfused parts.


• Should be free of foreign materials like string, plastic line, carbon, wood, metal, or other contaminants.


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


• Black spot diameter should not exceed 2mm.


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