Diffusion coefficients of neodymium (III) complexes in an equimolar NaCl — KCl — NdCl3 melt

The paper presents results of electrochemical behavior of neodymium trichloride in the NaCl — KCl melt. It was shown that the process of neodymium electroreduction in the NaCl — KCl — NdCl3 melt proceeds in two stages. It was established by using the diagnostic criteria of voltammetry that the discharge process of Nd (III) to Nd (II) at the potential sweep rate in the range of 0.6 ≤  ≤ 1.0 V · s-1 is not complicated by reaction disproportionation. In this study diffusion coefficients and activation energy of diffusion for Nd (III) complexes in the NaCl — KCl melt were determined.
