Industrial silicon powder, also known as metallic silicon powder, is a silver-gray or dark gray powder with metallic luster, high melting point, good heat resistance, high resistivity, and high antioxidant effect.
Product Usage:
1. metal silicon powder is widely used in refractory materials and powder metallurgy industries to improve the high-temperature resistance, wear resistance and oxidation resistance of products.
2. In the organic silicon chemical industry, si metal powder is the basic raw material for the synthesis of organic silicon polymers, which improves the high temperature resistance, electrical insulation, corrosion resistance, anti-corrosion, waterproof and other characteristics of the product.
3. In the metallurgical casting industry, High Purity Silicon Metal Powder is used as a non-ferrous alloy additive and silicon steel alloy agent to improve the hardenability of steel.
