Voltammetric and Chronopotentiometric Study of Nonstationary Processes at the Oxygen-Evolving Anodes in KF–NaF–AlF₃–Al₂O₃ Melt

Abstract:

Abstract. Some features of behavior and kinetic of the anodic processes for the platinum and Cu–Fe–Ni alloy in the KF–NaF–AlF₃–Al₂O₃ melts at 1025–1055 K have been studied by cyclic voltammetry and chronopotentiometry.The obtained results allowed us to conclude that mechanisms of the anodic processes at the platinum and Cu–Fe–Ni alloy are similar. Both mechanisms include the oxidation stage of electrode material. A rate of this stage is determined to depend significantly on the melt temperature.
