Fused Silica Product Description

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

Discover our high-quality fused silica products:

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 a versatile material for refractory applications.

Key Features:

• High purity silica sand (SiO2 > 99%) sourced locally from Donghai/Xinyi


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


• Available in fused silica lump, sand, and powder forms

Benefits:

• Excellent stability for highly cyclical applications


• Customizable products tailored to customer requirements


• Ensured quality and purity for optimal performance

Choose Lianyungang Chemsize for top-notch fused silica products that meet your refractory needs!

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 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 any 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.
