Description
The physical-chemical properties of high disperse magnetite and 3d-metal spinel ferrite phases formed on the Steel-3 surface, when it was contacting with water dispersion medium and air, were studied by various techniques including X-ray diffraction analysis, X-ray fluorescence spectroscopy, thermo-gravimetric and differential thermal analysis, scanning electron microscopy, Fourier transform infrared spectroscopy, electrophoresis, and magnetometry. The substitution of cobalt, nickel, zinc or copper cations for ferrous iron in the crystal lattice of magnetite was proposed to inhibit corrosion processes on the steel surface. The production of the protective 3d-metal spinel ferrite film on the steel surface was found as a simple way to decrease the corrosion rate, in general, and, hence, enlarge the technical lifetime of canister and container material used in the geological storages of high active nuclear wastes.
