Production Process

Fused Silica Product Description

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

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 fused silica a versatile material for refractory applications, such as aluminum launders.

Our Raw Materials

We carefully select high-purity silica sand (SiO2 > 99%) from local 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.

Packaging & Shipping

Our Fused Silica Powder is ideal for various applications including ceramic welding, investment casting, powder coating, and more. With a high purity of SiO2 99% min, low iron content, and excellent thermal properties, it is a versatile material for industrial use.

Lianyungang Chemsize International Trading Co., Ltd. offers top-quality Fused Silica Powder for various applications, including ceramic welding, investment casting, and powder coating. With a fusion ratio, low iron content, and high purity, it is ideal for high-temperature resistance and thermal shock.

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


• Only conditional black dots are allowed, no other color dots


• Black spot diameter should not exceed 2mm


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