Abstract
The phase composition and particle shape of amorphous iron hydroxide-iron oxide precipitates were correlated with the oxidation state of iron in the starting solution, Fe2O3 : FeO ratio, and precipitation procedure (coprecipitation or successive precipitation) using Mössbauer spectroscopy, atomic absorption, lowtemperature nitrogen BET, and electron microscopy data. A correlation was established between the amount of iron(II) in the starting solution, the amount of the metastable phase γ-Fe2O3 in the precipitate, particle shape, and the activity of the final heat-treatment products—α-Fe2O3 and mixed oxides of iron.
