Production Process

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.

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 based on customer requirements.

Fused Silica Product Description

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.

Introducing Chemsize Fused Silica

As a leading supplier of raw materials and machinery for investment casting for over 30 years, we are proud to present Chemsize Fused Silica. Many foundries use Zircon Flour for their primary slurry, but due to rising prices and limited supply, we recommend using Fused Silica flour for the following reasons:

• Better particle shape for improved primary slurry quality


• Decreased material consumption due to Fused Silica's lower density


• Increased permeability and porosity for better shell quality


• Easier knock-out and faster leaching and shell removal


• Consistent and sustainable sourcing from the world's largest Fused Silica production area


• Cost-effective pricing at US$0.56/kg FOB LIANYUNGANG PORT

Fused Silica Applications

Our Fused Silica is ideal for induction furnace lining ramming material, offering high purity and reliable performance. It is suitable for various applications in medium frequency furnaces, including melting different types of metals and alloys.
