Production Process

Fused Silica Production Process

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

Discover our high-quality fused silica products:

• Fused Silica: High purity quartz sand melted to form glass


• Features: High volume stability, low volumetric expansion, and exceptional purity


• Applications: Ideal for refractory applications like aluminum launders

At Lianyungang Chemsize, we source our raw material from high purity silica sand (SiO2 > 99%) in Donghai/Xinyi. The silica sand is melted at temperatures of 2000-2300 ºC to create amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder based on customer specifications.

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 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 string, plastic, 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.
