Third Party Test Report

Production Process

Product Description:

At Lianyungang Chemsize International Trading Co., Ltd., we specialize in the production of high-quality fused silica. Our fused silica is derived from high purity quartz sand, melted at temperatures between 2000-2300 ºC to form a glassy ingot of amorphous silicon dioxide. This material offers exceptional stability, low volumetric expansion, and high purity, making it ideal for various refractory applications.

We meticulously select high purity silica sand (SiO2>99%) from Donghai/Xinyi as our raw material, ensuring top-notch quality. Our fused silica products are available in lump, sand, and powder forms, tailored to meet the specific requirements of our customers.

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 resulting material is 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:

1. Must not contain any unfused parts.


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


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


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.
