Аннотация: Electrochemistry of Ni, Fe and Cu metals as well as their binary alloys is reported. To determine the characteristic potential regions of certain redox processes in cryolite-alumina melts, cyclic voltammetry, chronopotentiometry, and preparative potentiostatic electrolysis of oxide dissolved in the melt are applied. The nature of tПоказать полностьюhe electrolysis products, as well as the oxide films formed under open circuit and in the course of anodic polarization is clarified by means of X-ray powder diffraction and scanning electron microscopy (SEM) with EDX analysis. Finally, some general trends of selective dissolution and oxidation for binary systems are formulated in the context of predicting the role of each component in the multicomponent alloys tested as future inert anodes.
