Coefficient De Diffusion De Cu(I) Déterminé Par Différentes Méthodes Dans Les Chlorures Alcalins Fondus a 450°C

The interdiffusion coefficient of Cu(I) in three melts, LiCl-KCl (58–42% mol.) LiCl-CsCl (55–45% mol.), LiCl-KCl (70–30% mol.) at 450°C for the two first and 457%dGC for the last one has been measured by different electrochemical methods: chronopotentiometry, cyclic voltammetry, pulse polarography and chronoamperometry, Chronopotentiometry gives systematically lower values for the diffusion coefficient. No significant influence of the nature of the solvent on the diffusion coefficient was observed.
