MOLTEN SALT ELECTROLYZING VESSEL FOR METAL PRODUCTION AND PROCESS FOR PRODUCING METAL THEREWITH

摘要

An electrolyzing vessel for electrolyzing a metal chloride to thereby produce a molten metal, adapted to effectively avoid any reverse reaction between molten metal formed on negative electrode and chlorine gas formed on positive electrode. The molten salt electrolyzing vessel for metal production is one having an electrolyzing vessel main body for holding an electrolytic bath and, immersed and arranged in the electrolytic bath, a positive electrode and a negative electrode, characterized in that the molten salt electrolyzing vessel is divided by a first diaphragm and a second diaphragm into three spaces to thereby provide a negative electrode compartment partitioned by the electrolyzing vessel main body and the first diaphragm and including a negative electrode, an intermediate compartment partitioned by the first and second diaphragms and a positive electrode compartment partitioned by the electrolyzing vessel main body and the second diaphragm and including a positive electrode so that the electrolytic bath generates a circulating flow from the intermediate compartment toward the negative electrode compartment.
