Silicomanganese a ferroalloy composed chiefly of silicon and manganese, it is smelted by carbon reduction in ore heat-treating furnaces. It is primarily made up of 65-70% manganese,16- 25% silicon and 1-2.5% carbon.
Usage : it is used as a deoxidiser and alloying additive in the smelting of steel as well as in this melting of ferromanganese with reduced carbon content by the silicothermic process. It is also used as a raw material in the production of metallic manganese
