Production Process

Fused Silica Production Process

Welcome to Lianyungang Chemsize International Trading Co., Ltd.

Discover our high-quality fused silica products, meticulously crafted through a precise production process:

Fused Silica Features:

• High purity quartz sand melted to form glass


• High volume stability and low volumetric expansion


• Perfect for refractory applications

Production Process:

We source high purity silica sand (SiO2 > 99%) from Donghai/Xinyi. The sand is melted at 2000-2300 ºC to create amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder based on customer specifications.

Choose Chemsize for top-notch fused silica products tailored to your needs!

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 material is then specially engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are designed for making 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 not have any foreign materials like string, plastic, carbon, wood, metal, or other contaminants.


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


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.
