  • Electrode for electrochemical processes and production method therefor
    Patent number: 4361603
    Abstract: An electrode for electrochemical processes comprises an electrically conductive base topped with a layer of active compound composed of, wt %:______________________________________ metal oxide from the platinum group 5-45 at least one metal oxide from the iron and manganese group 19-94.9 boron oxide 0.1-50 ______________________________________A method of fabricating the electrode for electrochemical processes involves deposition of an active compound on an electrically conductive base, the steps comprised in the procedure being application thereto of a solution made up of a thermally decomposed boric compound, at least one thermally decomposed metal compound from the iron and manganese group, and at least one thermally decomposed metal compound from the platinum group, and thermal treatment of said base at a temperature of 360.degree. to 500.degree. C.
    Type: Grant
    Filed: August 29, 1980
    Date of Patent: November 30, 1982
    Inventors: Vladimir L. Kubasov, Leonid I. Jurkov, Vladimir B. Busse-Machukas, Georgy N. Kokhanov, Florenty I. Lvovich
  • Electrode for electrochemical processes
    Patent number: 4329219
    Abstract: An electrode comprising a current-conducting base having deposited thereon an active mass of the following composition, in percent by mass:______________________________________ silica 10-90 platinum group metal oxides 5-45 oxides of passivating metals 5-45. ______________________________________The electrode of this invention is useful as anodes in the production of chlorine and caustic soda, as well as in electrolytic processes of producing chlorates and hyperchlorites.
