Fused Silica Product Description

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

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 resulting material is 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


• Black spot diameter should not exceed 2mm


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

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 advantages:

• Better particle shape for improved primary slurry quality


• Reduced material consumption due to lower density


• Increased permeability and porosity for better shell quality


• Easier knock-out and shell removal process


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


• Competitive pricing at US$0.56/kg FOB LIANYUNGANG PORT

Induction Furnace Lining Ramming Material

The intermediate frequency furnace ramming material, also known as the intermediate frequency furnace lining material, is available in acidic, neutral, and alkaline variants. These materials are widely used in coreless medium frequency furnaces and core induction furnaces for melting various metals and alloys.
