Product Description
We supply various grades of metallic silicon, including 553, 441, 421, 3303, 2202, 1101, etc. Our products comply with GB/T 2881-2014, ASTM and international standards, ensuring high purity (Si ≥98.5%) and customizable specifications for various applications. Our business covers the world. We look forward to cooperating with you.
In some large-scale industrial production, such as steel smelting and aluminum alloy manufacturing, it can be directly put into the furnace for smelting. Granular metal silicon has a larger specific surface area and can react with other substances more quickly in chemical reactions. It is often used in the fields of fine chemicals and refractory materials. It can participate in the reaction more evenly and improve product quality.
