Abstract

An anode composition is used as the sole source of aluminum and comprises an aluminous material such as aluminum oxide and a reducing agent such as carbon. Electrodeposition is achieved at low temperatures and low electrical potential by the electrolysis in a fused salt containing the composite anode. The anode reacts to produce aluminum ions during the electrolysis, aluminum compound ionized at the anode is electrolytically reduced to molten aluminum at the cathode and an anion formed at the anode reacts to produce CO2 gas at the anode. In one operational mode a porous membrane passes electrolyte or other dissolved material while withholding undissolved impurities. Aluminum may be electrodeposited, at a temperature as low as the melting point of the metal and with the use of an all fluoride containing bath and the composite anode. Dimensionally stable cells for the electrodeposition have sloped walls forming electrodes that permit the maintenance of a reduced anode current density as well as anode- cathode spacing when using the low temperature non-aggressive baths permissible with the particular composite anode composition.
