The elctrochemical 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(Ⅲ)in the melt at 827℃was found to be 9.7×105cm2/s.
