Description
Summary:Mössbauer spectroscopy and X-ray diffraction were used to study iron powders in process of their preparation by high temperature reduction of α- FeOOH in hydrogen. It was found that the following conversions occur both in the bulk and on the surface of the particles obtained in process of reduction of α-FeOOH up to α-Fe:α-FeOOH → Fe 3O 4 → α-Fe. After the complete reduction a slight quantity of the γ-FeOOH phase is present in the surface layer of iron particles in contrast to the bulk.
