Production Process

Fused Silica Product Description

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

Discover our high-quality fused silica products, meticulously crafted to meet your refractory needs.

Product Features:

• High purity quartz sand (SiO2 > 99%) sourced locally from Donghai/Xinyi


• Exceptional volume stability and low volumetric expansion


• Versatile material suitable for various refractory applications

Production Process:

Our fused silica is produced by melting high purity silica sand at temperatures ranging from 2000-2300 ºC, resulting in amorphous silicon dioxide glassy ingots. These ingots are then processed into fused silica lumps, sand, and powder according to customer specifications.

Fused Silica Product Description

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

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 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:

• Must not contain any unfused parts


• No foreign materials like string, plastic, carbon, wood, metal, or other contaminants


• Only conditional black dots are allowed


• Black spot diameter must not exceed 2mm


• Total black dots should be less than 10 per square meter
