Abstract
The formation of gamma-Fe2O3 by thermal decomposition of a mixture of Fe(II)- and Fe(III)-oxalate salts was investigated using X-ray diffrac tion, Fe-57 Mossbauer spectroscopy and FT IR spectroscopy. It was foun d that the ball-milling of the starting chemicals, at the concentratio n ratio for the Fe3O4 formation, suppressed the formation of alpha-Fe2 O3 as the phase associated with gamma-Fe2O3 during the thermal decompo sition process. The correlation of the results obtained by X-ray diffr action, Fe-57 Mossbauer spectroscopy and FT IR spectroscopy was shown.
