Reduction of Iron Oxides with Hydrogen—A Review

Wüstite is formed during the reduction of hematite and magnetite above 570 °C. Initially, wüstite has a composition near the FeO/Fe 3 O 4 equilibrium. If the reduction continues, the ratio of Fe to O changes until reaching equilibrium between Fe and FeO. Further reduction leads to the formation of an iron-oversaturated wüstite layer.
