المستخلص: |
The mechanism of dysprosium chloride complexes electro reduction on the tungsten and silver electrodes in NaCl-KCl - CsCl melt at 823 K has been studied by linear and cyclic voltammetry. Some kinetic parameters of processes were calculated. It was shown that the tungsten electrode was indifferent to dysprosium, which were reduced on the surface. We found that the discharge mechanism of dysprosium chloride complexes was described by three-electron step when the steady-state conditions of polarization were limited by the mass transfer stage. The conditions of non-stationary polarization made the slowness of charge transfer stage. The diffusion coefficient was calculated for DyCl63- ions diffusion coefficient was (0.50 ± 0.2). 10-5 cm2/s |
