Electrochemical measurements of YCl3, ScCl3, GdCl3 and MgCl2 were obtained in the molten eutectic LiCl-KCl at 773 K using a three-electrode configuration. Tungsten rods were used as the working and counter electrodes. Three reference electrodes of differing composition (glassy carbon, nickel wire, and Ni/NiO) were utilized to acquire electrochemical measurements of the analyte salts. Cyclic voltammetry data were analyzed to determine diffusion coefficient and exchange current density values. The measured cyclic voltammograms were normalized with respect to both lithium reduction and chloride ion oxidation potentials. Such a normalization technique is effective for comparing experimentally obtained cyclic voltammetry data to those which have been published. Analysis of experimentally obtained results indicates the relation of electrode reactions (e.g. differences of reduction potentials) are independent of the choice of reference electrode. Additionally, the choice of reference electrode does not affect the electrochemical window, exchange current density, and diffusion coefficient values.
