Bismuth has been investigated as a potential liquid electrode for molten salt electrorefining, but the electrochemical behavior of Bi3+/Bi redox couple has received scant attention in LiCl–KCl and LiCl–KCl–CaCl2 eutectics. Electroanalytical techniques were used to determine properties of Bi3+/Bi. Diffusivities of 6.71 and 8.93 × 10–6 cm2 s–1 and standard apparent potentials of 0.1166 and 0.1187 V versus Ag/AgCl (4.75 mol%) were recommended for BiCl3 in LiCl–KCl and LiCl–KCl–CaCl2 eutectics, respectively, at 680 ± 3.1 K. The ICP-MS analysis of BiCl3 content limited the accuracy of the results. Furthermore, the reliability of the results improved with a more thorough drying procedure for CaCl2.
