Iron silicide is used in deoxidation and alloying of steel melts, alloying of cast iron charges and melts (Iron foundries), silicothermic reduction of precious metals (chromium, molybdenum and vanadium) and others (Nb, W), Production of some inoculants and nodulisers by alloying (melting). High purity iron silicide is used to produce high permeability steel for electric transformers, production of FeSiMn, FeSiN and SiMn- alloys. It is also used as metal filler.
