  • Electrodeposition of ruthenium-iridium alloy
    Patent number: 4189358
    Abstract: Ruthenium-iridium electrodeposits are prepared from aqueous acid solution containing ruthenium, iridium, a fluoborate salt, fluoboric acid, and optionally sulfamic acid. The baths are especially useful for preparing insoluble anodes.
    Type: Grant
    Filed: July 14, 1978
    Date of Patent: February 19, 1980
    Assignee: The International Nickel Company, Inc.
    Inventors: Anthony J. Scarpellino, Jr, William G. Borner
  • Iridium compound and preparation thereof
    Patent number: 4174378
    Abstract: Iridium compounds are produced by refluxing a diammonium hexahalo salt of iridium and sulfamic acid in an aqueous medium for more than thirty hours. When the diammonium hexachloro salt of iridium is used, the iridium product is an olive green salt having a melting point above 350.degree. C. The iridium products are useful as constituents of electroplating baths.
    Type: Grant

  • Composite electrode for electrolytic processes
    Patent number: 4157943
    Abstract: A composite electrode especially suitable for electrowinning processes comprising an electrically conductive substrate having on at least a part of its surface a multilayer coating, said coating comprising:(a) a barrier layer directly on the substrate;(b) a ruthenium dioxide-containing non-electrodeposited surface layer; and(c) between the barrier layer and the surface layer, an intermediate layer consisting of an electroplated ruthenium-iridium deposit, said ruthenium-iridium deposit being at least partially in an oxidized state.
