FeSi is used as a source of silicon to deoxidize steel and other ferrous alloys. This prevents the loss of carbon from the molten steel; ferromanganese, spiegeleisen, silicides of calcium, and many other materials are used for the same purpose. It can be used to make other ferroalloys. Ferrosilicon is also used for manufacture of silicon, corrosion-resistant and high-temperature resistant ferrous silicon alloys, and silicon steel for electromotors and transformer cores. In the manufacture of cast iron, ferrosilicon is used for inoculation of the iron to accelerate graphitization.
