Sažetak
Fourier transform infrared (FTIR) spectroscopic measurements, performed in
the far-IR region (200-800 cm(-1)) on binary coprecipitated Ni(II)-Fe(III)
hydroxides (20-60 at.% Fe/(Ni + Fe)), are presented and discussed. Heating
the sample containing 60 at.% Fe to 600 degrees C, monitored by
differential scanning calorimetry (DSC) measurements, results in the
formation of a nickel ferrite structure from its precursor present in
binary hydroxides. The role of Fe-to-Ni ratio non-uniformities within the
surface and bulk of the binary hydroxide crystallites, as revealed by
Mossbauer measurements, Auger electron spectroscopy and depth profiling
performed previously, is also discussed with regard to the formation of
alpha-Fe2O3 and NiO impurities on thermal treatment.
