The preparation of massive oxides Zn1−xFexO by means of mechanicalmilling in diverse gaseous atmospheres and starting with different powder mixtureswas investigated. ZnO powder with 10 at.% admixture of Fe, FeO or Fe2O3, weremilled during 1, 4 or 16 h and characterized by X-ray diffraction and Mössbauerspectroscopy. Different phases were obtained according to the initial conditions(precursor used, atmosphere, etc.) and phase’s formation enthalpies.
