Abstract
Transformations of oxyhydroxides of iron(III), which are formed in the process of oxidation of iron(II) in Fe(OH)2 suspensions upon the hydrothermal treatment at 150–220°C in water and in aqueous solutions of potassium hydroxide with concentrations of 1–5 mol/L have been studied. The dependences of the phase composition and dispersity of the arising products and the morphology of α-Fe2O3 on the parameters of heat treatment and on the phase composition of FeOOH have been determined. Conditions for obtaining nanodisperse α-Fe2O3 with a lamellar shape of crystals have been refined.
