Third Party Test Report

Production Process

Fused Silica Production Process

Fused silica is high purity quartz sand that has been melted to form glass. Its high volume stability, low volumetric expansion, and high purity make fused silica a versatile material for refractory applications, such as aluminum launders.

Raw Material

We source high purity silica sand (SiO2 > 99%) from Donghai/Xinyi for our production process.

Manufacturing Process

The silica sand is melted at high temperatures (2000-2300 ºC) to form an amorphous silicon dioxide glassy ingot, which is then cooled and processed into fused silica lump, sand, and powder based on customer requirements.

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 specially engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour forms. These are designed for making 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 such as strings, plastic lines, carbon, wood, metal, or other contaminants


• Only conditional black dots are allowed


• Black spot diameter should not exceed 2mm


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