The author had already performed some investigations on the reduction equilibrium of iron oxides and proposed the reduction equilibrium diagram of Fe-C-O system. But the equilibrium on systems of Fe_3O_4-liquid oxide-CO/CO_2 mixed gas and wustite-liquid oxide-CO/CO_2 mixed gas, and the relation between oxygen pct. in liquid oxide and CO/CO_2 mixed gas had not been measured. These relations were shown by concluded lines in the diagram. Recently these equilibrium were measured by Darken and Gurry and the relations between oxygen pct. in wustite and CO/CO_2 mixed gas were clecked from the view point of the statistical thermodynamics by Takeuchi and Igaki. Referring to these results, the author corrected the reduction equilibrium diagram of Fe-C-O system, then established the reduction equilibrium diagram of Fe-H-O system by the calculation.
