Abstract: An electrochemical study of iron was carried out in KCl+LiCl+NaCl melt at 550ºC using a glassy carbon working electrode. Cyclic voltammetry showed that the Fe(II)/Fe(0) electron exchange is a soluble/insoluble reversible process. The diffusion coefficient of Fe(II) was calculated using cyclic voltammetry; 1.4×10-5 cm2 s-1. For the Fe(II)/Fe(III) red/ox reaction, analysis of the voltammograms suggests that the process is not reversible and is coupled with a chemical reaction. The stability of FeCl3 and the effect of equilibrium between FeCl3 and FeCl2 are also briefly discussed.
