  • Process of preparing a durable electrode by plasma spraying an intermetallic compound comprising cerium oxide and non-noble Group VIII metal
    Patent number: 5492732
    Abstract: Provided is a process for producing a durable low hydrogen over-voltage cathode. An interim coating is applied to a metallic substrate by plasma spraying an intermetallic compound comprising at least 10% cerium oxide by x-ray diffraction analysis and at least one non-noble Group 8 metal. The metallic substrate bearing the interim coating is then heated in a non-oxidizing atmosphere including an inert gas to produce the electrode.
    Type: Grant

  • Cathode for use in electrolytic cell and the process of using the cathode
    Patent number: 5324395
    Abstract: Durable low hydrogen over-voltage cathodes bearing a coating which has an outer layer which comprises at least 10% cerium oxide by XRD and at least one non-noble Group 8 metal. Such cathodes may be prepared by a process involving at least the steps of coating a metallic substrate with an interim coating comprising cerium oxide and at least one non-noble Group 8 metal by plasma spraying an intermetallic compound of cerium and nickel and heating the interim coating in a non-oxidizing atmosphere.
