Streszczenie: The nanodimensional magnesium ferrite materials Mg0.25Fe2.75O4, Mg0.5Fe2.5O4 and MgFe2O4 with different stoichiometry were prepared by co-precipitation procedure using MgCl2•6H2O, FeCl2•4H2O and FeCl3•6H2O and NaOH as precipitant. The physicochemical methods - X-ray diffraction analysis, Moessbauer spectroscopy and FTIR spectroscopy were performed to investigate the structural properties of obtained nanosize magnesium ferrite type samples. The registered experimental data were determined the presence of spinel ferrites and additional precursor phases as iron oxihydroxides and double layered hydroxides in ferrite materials Mgx Fe3-x O4 (x=0.5;1). In the case of magnesium ferrite sample Mgx Fe3-x O4 (x=0.25) the existence of non-stoichiometric spinel ferrite and intermediate phase - iron oxihydroxides were observed only.
