Production Process

Product Description:

At Lianyungang Chemsize International Trading Co., Ltd., we specialize in the production of high-purity fused silica. Our fused silica is derived from locally sourced silica sand with a purity level exceeding 99% (SiO2). Through a meticulous process of melting the silica sand at temperatures ranging from 2000-2300 ºC, we create a versatile material with high volume stability, low volumetric expansion, and exceptional purity.

Our fused silica is ideal for various refractory applications, including aluminum launders, due to its superior quality and performance. We offer fused silica in the form of lumps, sand, and powder, tailored to meet the specific requirements of our customers.

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 between 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 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 not have foreign materials like string, plastic, carbon, wood, metal, or other contaminants.


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


• Black spot diameter should not exceed 2mm.


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