The Application. Ferrosilicon is used in steelmaking and foundries as a source of silicon in production of carbon steels, stainless steels, and other ferrous alloys for its deoxidizing properties, to prevent loss of carbon from the molten steel (so called blocking the heat); ferromanganese, spiegeleisen, silicides of calcium, and many other materials are used for the same purpose.

The silicothermic process in the pre-prepared dolomite pellets is possibly a solid–liquid reaction since calcium silicide transformed into liquid alloy, which reduced diffusion resistance of silicon during the reduction process. The gas–film mass transfer may have some effect on the reduction kinetics but is not the major rate-limiting step.
