Abstract

Voltammetric and chronopotentiometric methods were used to study the electrochemical behaviour of copper in the NaF-AlF3-BaCl2 ternary melt at 750° C. Copper, graphite and platinum were used as electrode materials. It was shown that the electrochemical reduction of copper ions is a single step process, with the reversible exchange of one electron at a copper electrode. The value of the diffusion coefficient of the cuprous ion, determined by means of chronopotentiometry, isD =(2.8±0.3)× 10−5 cm2 s−1.
