Abstract

Mixed ferrite MnFe₂O₄ has been prepared by combustion synthesis method and subsequent heat treatment. The effects of annealing temperature and quenching conditions on phase compositions of the samples have been investigated by X-ray diffraction and Mössbauer spectroscopy. The results show that the combustion of Fe₂O₃, MnO₂ and Fe results in a series of mixtures of new phases, which convert to MnFe₂O₄ single spinel phase during subsequent heat treatment at 1200°C for 2h and rapid quenching. Moreover, combustion synthesis of MnFe₂O₄ can efficiently induce a redistribution of divalent and trivalent ions in the A and B sites.
