ժҪ he electrochemical behavior of dissolved Fe2O3 in 82��5CaCl2��17��5KF (mole percent, %) was studied using cyclic voltammetry, chronoamperometry, and galvanostatic electrolysis at 827 ��, and the deposits were characterized by XRD and SEM. Pure iron was deposited on a rotating cylinder (210 r/min) with a cell voltage less than -1��0 V. Deposition rate was controlled by diffusion on a molybdenum electrode. The diffusion coefficient of iron species Fe(��) in the melt at 827 �� was found to be 9��7��10-5 cm2/s.
