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 in aluminum launders or other highly cyclical applications.

At Lianyungang Chemsize International Trading Co., Ltd., we carefully select high-purity silica sand (SiO2>99%) from Donghai/Xinyi as our raw material. The silica sand is melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder according to customer requirements.

Fused Silica Product Description

Fused Silica Products by Lianyungang Chemsize International Trading Co., Ltd.

Fused Silica is meticulously crafted from high purity crystal silica sourced from China Donghai-Xinyi. Through an electric fusion process at temperatures ranging from 1800-2000ºC, the silica is transformed into amorphous Silicon dioxide. Our Fused Silica is available in various forms including lumps, cullet, ingots, sand, grain, granular, and powder flour, tailored for applications like PV fused silica crucible, thermal ceramic, refractory, EMC investment casting ceramic shell, and more.

Appearance and Specifications:

• No unfused parts are allowed.


• Foreign materials like string, plastic line, carbon, wood, metal, or other contaminants are strictly prohibited.


• Only conditional black dots are permissible.


• Black spot diameter should not exceed 2mm.


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