Abstract The layered system Fe/FeO/Fe3O4/Fe2O3/O2 is formed during the oxidation of iron in air or oxygen at temperatures above 580°C. Phase transformations as well as transfer of ions, electrons, and vacancies occur at the phase boundaries; these phenomena have not been fully described in the literature. Equations are given in this paper which allow a complete estimation of the rates of all partial reactions. Fe3O4 is formed by phase transformation of Fe2O3. The formation of Fe2O3 is described theoretically, but a decision from which of several reactions Fe2O3 is really formed is not possible because of experimental difficulties.
