  • Process and anode for molten salt electrolysis
    Patent number: 4448654
    Abstract: An uncoated ceramic anode comprising titanium having a formal valence of +4; titanium having a formal valence of +3; and a dopant which prevents at least a portion of the titanium +3 from converting to titanium +4 when the ceramic anode is at operating cell conditions. The ceramic anode may have an electrically conductive substance enclosed in its interior. The substance serves to transfer electrical energy from a power source to the ceramic member. These anodes are particularly useful when used in molten salt electrolytic cells because they give good electrolytic production rates while demonstrating exceptionally low wear rates.
    Type: Grant
    Filed: June 18, 1982
    Date of Patent: May 15, 1984
    Assignee: The Dow Chemical Company
    Inventors: Stanley F. Spangenberg, Arlington L. Finley, D. James Searson
