  • Electrode for electrolytic processes
    Patent number: 4012296
    Abstract: An electrode, for use in electrolytic processes, especially as an anode for use in the electrolysis of aqueous solutions of alkali metal halides, comprises a valve metal substrate coated on at least a portion of the surface thereof with a mixed oxide of hafnium and ruthenium wherein the molar ratio of ruthenium:hafnium is from about 0.25 to about 4.0.
    Type: Grant
    Filed: October 30, 1975
    Date of Patent: March 15, 1977
    Assignee: Hooker Chemicals & Plastics Corporation
    Inventors: Donald E. Stephens, Tilak V. Bommaraju
  • Electrolytic anode
    Patent number: 3969217
    Abstract: An improved electrode, useful as an anode for the electrolysis of brines comprises an electrically conductive substrate having adhered thereto and extending over at least a portion of the surface thereof, a coating of mixed oxides comprising about 10 to about 80 mole percent indium oxide and about 10 to about 90 mole percent of a platinum group metal oxide. Up to about 20 mole percent of tin oxide may be incorporated in the coating to lower the electrical resistivity thereof.
    Type: Grant
    Filed: October 7, 1974
    Date of Patent: July 13, 1976
    Assignee: Hooker Chemicals & Plastics Corporation
    Inventors: Tilak V. Bommaraju, Donald E. Stephens
  • Anode for electrolytic processes
    Patent number: 3950240
    Abstract: An electrode useful as an anode for the electrolysis of aqueous solutions of ionizable chemical compounds, and especially the electrolysis of brines comprises an electroconductive substrate, such as a valve metal having a coating thereon of electroconductive tin oxide containing about 0.1 to about 15 mole percent of niobium based on the moles of tin. An additional electrocatalytic phase may be present as a minor component of the tin oxide coating and/or as a coating thereon.
