Abstract

A diagram of the stable state of chloride phases in equilibrium with the [Fe-Mn]s solid solution has been constructed for the Fe-Mn-Cl-H-O system. It is shown that during chlorination at 1323-1423°C oxides are fully reduced. Chlorination is experienced almost exclusively by manganese, while iron passes into the solid solution. With the aid of the diagram it is possible to determine the composition of gaseous phases ensuring stability of gaseous manganese chlorides for any desired manganese concentration in iron.
