Abstract
Although the activity coefficients and diffusion coefficients of LaCl3 in molten LiClKCl salt have been extensively studied, the data on the electrochemical properties of La(III)/La reaction in the melt are very scarce. Among the few measurements, up to five orders of magnitude discrepancies for the reaction rate constant k0 have been reported. In the present study, potentiodynamic polarization measurements at different LaCl3 concentrations (1
