Pavlenko, O. Obtaining of the homogeneous iron oxide phases doped with of Co2+, Cu2+, Zn2+, and Ni2+ cations and their stabilization using higher carboxylic acids

The work is devoted to the development of the methodology of chemical and thermal homogenization of oxide-hydroxide mixtures obtained in open systems based on iron and steel at the origin of the process of rotational corrosion dispersion (RCD), with the formation of nanosized ferrispinel particles doped with cationic surfaces higher carboxylic acids with the formation of colloidal stable organosols. Determination of the single colloid-chemical mechanism of the formation of nanosized spinel ferrite particles when the rotation corrosion dispergation (RCD) method, performed in the open-air system in the presence of iron (steel), was applied has been found as the main result of the present work. It lied in the interaction of the products of Fe(II)-Fe(III) layered double hydroxide (LDH) dissolution with transition 3d-metal aquahydroxoforms.
