MACROKINETICS OF SOLID-PHASE ELECTROCRYSTALLIZATION OF COPPER IN ION-EXCHANGE MATRIX - DISTRIBUTIONS OF THE POTENTIAL AND PROCESS RATE

The distribution of the polarization characteristics throughout the de pth of the granular redoxite layer during electrochemical reduction wa s studied. The rate of metal solid-phase electrocrystallization in the ion-exchange matrix is determined by the overpotential of the limitin g stage and the ohmic resistance of the solid phase. The ohmic resista nce varies throughout the depth of the electrode when the metal compon ent is accumulated.
