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 aluminum launders.

We source high-purity silica sand (SiO2 > 99%) from Donghai/Xinyi for our production process. The sand is melted at temperatures of 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.

Company Name: Lianyungang Chemsize International Trading Co., Ltd.

Fused Silica Product Description

Fused Silica Making Process

Fused Silica is produced from high purity crystal silica sourced from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000ºC to create amorphous Silicon dioxide. The material is then specially processed 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 be free of foreign materials like strings, plastic lines, carbon, wood, metals, or other contaminants.


• Only conditional black dots are allowed; all other color dots are prohibited.


• 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. Most 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 advantages:

• Particle shape: Our Fused Silica offers superior particle shape crucial for primary slurry.


• Decreased material consumption: With half the density of Zircon, Fused Silica allows for reduced material usage.


• Increased permeability and porosity: Fused Silica's lighter density improves shell permeability and porosity.


• Easier knock-out: Fused Silica breaks down easily after pouring, simplifying shell removal.


• Faster leaching and shell removal: Fused Silica aids in the leaching process and facilitates shell material removal.


• Consistency and sustainability: Our Fused Silica from the world's largest production area in China ensures consistency and availability.


• Affordability: Fused Silica is cost-effective at US$0.56/kg FOB LIANYUNGANG PORT.
