The reduction of Fe 2 O 3 with hydrogen was studied. The thermodynamic analysis of the process implied that temperature-programmed reduction of the oxide should proceed in three steps, i.e. Fe 2 O 3 → Fe 3 O 4 → "FeO" → Fe, at X H 2 O / X H 2 ratio over 0.35, but in two steps, i.e. Fe 2 O 3 → Fe 3 O 4 → Fe, below that value.
