421 Silicon Metal

Ferrosilicon is widely used in refractory materials and the powder metallurgy industry as an excellent antioxidant. Adding ferrosilicon to refractory materials allows it to react with oxygen first, forming new mineral phases that seal pores, increase density, and prevent the penetration of slag and iron, thereby enhancing the product's high-temperature resistance, wear resistance, and oxidation resistance. As a result, it is extensively applied in refractory materials such as steelmaking furnaces, kilns, and kiln furniture. In the metallurgical casting industry, ferrosilicon serves as a non-ferrous alloy additive and silicon steel alloying agent, improving the hardenability of steel. Ferrosilicon can also be used as a reducing agent for certain metals and in new ceramic alloys, among other applications. Our factory can provide various specifications and models of ferrosilicon blocks, granules, and powders according to customer requirements.
