Third Party Test Report

Production Process

Product Description: Fused Silica

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 an extremely useful and versatile material for refractory applications, such as in aluminum launders or other highly cyclical applications.

At Lianyungang Chemsize International Trading Co., Ltd., 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 an amorphous silicon dioxide glassy ingot, which is then cooled and processed into fused silica lump, sand, and powder according to customer specifications.

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 lumps, cullet, ingots, sand, grain, granular, and powder flour forms. These are designed for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.

Fused Silica Sand Appearance and Specifications:

1. Must not contain any unfused parts.


2. Should be free of foreign materials such as strings, plastic lines, carbon, wood, metal, or other contaminants.


3. Color dots are only acceptable if they are black and meet specific conditions.


4. Black spot diameter should not exceed 2mm.


5. Total black dots quantity should be less than 10 per square meter when opening the big bag.
