Effect of the Surface Structure of the Co3O4 Oxide on the Dissolution Kinetics in an Acid Electrolyte

  • Published:
Russian Metallurgy (Metally) Aims and scope


The kinetics of dissolution of the commercial powdered Co3O4 cobalt oxide in an aqueous H2SO4 solution of various concentrations is experimentally studied. Electron microscopy and X-ray diffraction analysis are used to study the effect of the initial state of the surface structure of the cobalt oxide on the kinetic characteristics of dissolution. The shape and sizes of Co3O4 particles and the character of their surface distribution are determined. The ICDD powder material database is used to identify the structure of the oxide samples, and the Co3O4 oxide is found to be represented by the α form of cubic symmetry. Kinetic curves are constructed and the kinetic parameters of the process are calculated. The results obtained can serve as a contribution to the generalization of the experimental material accumulated to determine the laws of dissolution of the oxide phases of cobalt and other transition metals in acid electrolytes of various compositions.
