摘要
The electrochemical behavior of dissolved Fe2O2 in 82.5CaCl2-17.5KF （mole percent, %） was studied using cy clic 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 9.7×10^-5 cm^2/s.
