Abstract: The electrochemical separation of aluminum-silicon alloy in the low temperature molten salt AlCl3-NaCl-KCl at constant current deposition was studied. Aluminum-silicon alloy for the anode electrode and stainless steel for the cathode electrode were used. The effects of temperature, current density and time on the current efficiency and the morphology of deposited aluminum were analyzed by the scanning electron microscope and X-ray diffraction. The results show that, when the current density is 50mA/cm2, the maximum current efficiency can reach 93.7% at 200��C for 60min using Si-50%Al(mass fraction) as anode electrode, and there is 90.4% silicon in the anode slime.
