Product Description
Silicon metal powder refers to the raw material used in refractory materials and powder metallurgy industry. Metal silicon powder is made of metal silicon through grinding, screening and other processes of powder material. Its chemical composition is basically the same as metal silicon, the content of the main component silicon element is more than 98%, and the remaining impurities are iron, aluminum, calcium and so on. Its appearance is silver gray or dark gray powder, with metallic luster, high melting point, good heat resistance performance, high resistivity, high oxidation, good liquidity, specific surface area, high activity.
1. Silicon metal powder is widely used in refractory materials and powder metallurgy industries to enhance the high-temperature resistance, wear resistance and oxidation resistance of products. Its products are widely applied in steelmaking furnaces, kilns and kiln furniture.
2. In the organic silicon chemical industry,Silicon metal powder serves as the basic raw material for the synthesis of organic silicon polymers, such as for the production of silicon monomers, silicone oil, silicone rubber and preservatives, thereby improving the high-temperature resistance, electrical insulation, corrosion resistance, anti-corrosion and water resistance of products.
