Abstract: Mechanism of phase formation at oxidation of water solutions $\mathrm{FeSO_4}$ and (or) suspensions $\mathrm{Fe(OH)_2}$ at quasi-constant temperature and $\mathrm{pH}$ values is analyzed. Obtained nanodispersed materials are studied by means of $\mathrm{X}$-ray phase analysis, $\mathrm{X}$-ray fluorescence analysis, infrared spectroscopy, raster electron microscopy, thermogravimetric analysis and mass-spectrometry. Dependence of phase and disperse product content on parameters of synthesis is determined.

Keywords: phase formation, nanodispersed, oxy hydroxides of ferrum (III).
