ABSTRACT:
A low temperature salt bath for the electrolysis of metal oxides to produce the corresponding metal. The bath comprises a first salt, comprised of at least one fluoride salt, and a second salt, comprised of at least one chloride salt. The fluoride salt increases the metal oxide solubility in the molten salt bath, and the chloride salt reduces the bath liquidus temperature of the salt bath. The preferred process of practicing the invention includes using an anode consisting essentially of carbonaceous material and having an effective surface area about equal to the projected surface area of the anode.
