Fused Silica Production Process

Fused silica is a high-purity quartz sand that has been melted to form glass. Its high volume stability, low volumetric expansion, and high purity make it ideal for refractory applications.

Key Features:

• High purity silica sand (SiO2 > 99%) sourced locally


• Melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingot


• Available in fused silica lump, sand, and powder

Benefits:

• Excellent stability for highly cyclical applications


• Versatile material suitable for aluminum launders and more


• Customizable products tailored 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 transforms into amorphous Silicon dioxide. Our Fused Silica is available in various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour, tailored for creating PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.

Appearance and Specifications:

• No unfused parts are permitted.


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


• Except for conditional black dots, all color dots are not allowed.


• Black spot diameter exceeding 2mm is unacceptable.


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