Abstract

Metallic iron can be formed by reacting Fe3O4 with Zn in a ball mill. A mixed Fe-Zn oxide forms first, followed by decomposition into Fe and ZnO upon further milling. A large amount of Zn remain dissolved in the bcc phase and a fraction of the Fe retains an oxidized state. Decomposition can also be achieved by annealing the intermediate oxide. This process is investigated by thermomagnetic measurements, XRD, and Mossbauer spectroscopy. It is shown that the intermediate phase decomposes at relatively low (300-400°C) annealing temperatures. The separation of Fe and Zn between the metal and oxide phases of the end product is more complete than found in samples prepared by milling alone.
