Industrial silicon powder: What are the uses of high-purity metal silicon powder?
High-purity metal silicon powder metallurgy metal silicon, solid dark gray, metallic luster, high melting point, good heat resistance, high resistivity, good conductor in high-temperature molten state, hard and brittle. It is widely used in the development of aluminum alloy catalysts, non-ferrous metal deoxidizers and special steel smelting. It can also be used as an additive for special steel, an alloying agent for strict silicon steel, and a deoxidizer for smelting special steel and non-ferrous alloys.
