FIELD: technology for electrolytic restoration of metal oxides in solid state.
SUBSTANCE: electrolytic cell for restoration of metal oxide, for example, such as titan dioxide, includes anode composed of carbon and cathode created at least partially from oxide of the metal being restored. Electrolytic cell also includes membrane, which is penetrable for oxygen anions and impenetrable for carbon in ionic and nonionic forms, situated between cathode and anode for preventing migration of carbon to cathode as a result. Restoration method is performed in electrolytic cell under potential, which ensures electrolytic restoration of aforementioned metal oxide.
EFFECT: lower concentration of carbon in metal.
