The products of the above reactions, the oxides silica, manganese oxide, phosphate, and ferrous oxide, together with burnt lime calcium oxide CaO added as flux, form the slag. Burnt lime has by itself a high melting point of 2,570 C 4,660 F and is therefore solid at steelmaking temperatures, but when it is mixed with the other oxides, they all melt together at lower temperatures and thus form the slag.
