Production Process

Fused Silica Production Process

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

At Lianyungang Chemsize, we specialize in the production of high-purity fused silica for various refractory applications. Our fused silica is made from locally sourced high-purity silica sand with a SiO2 content of over 99%. Through a meticulous process of melting the silica sand at temperatures between 2000-2300 ºC, we create amorphous silicon dioxide glassy ingots that are then further processed into fused silica lumps, sand, and powder to meet our customers' specific requirements.

Key Features:

• High volume stability


• Low volumetric expansion


• High purity (SiO2>99%)

Benefits:

• Versatile material for refractory applications


• Suitable for highly cyclical applications like aluminum launders

Choose Lianyungang Chemsize for top-quality fused silica products tailored to your 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 resulting material is 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:

• Must not contain any unfused parts.


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


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


• Black spot diameter should not exceed 2mm.


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