The nanosize iron–oxygen-structures’ nucleation in Fe0–H2O–O2 system on the iron surface, near-surface layer and dispersion medium is investigated. As revealed, the phase composition and structure of iron monohydrates and oxides change depending on phase-formation process parameters. Regularities of nano- and microsize iron–oxygen-structures’ formation in Fe0–H2O– O2 system are analyzed depending on chemical composition and pH value of dispersion medium, oxidant access and temperature. As shown, the control of physicochemical parameters of phase-forming process in the systems based on Fe0–H2O–O2 can be one of the control methods for fabrication of iron– oxygen-compounds’ monophases of different crystallographic modifications.
