  • Method of preparation of dispersion strengthened silver electrical contacts
    Patent number: 4018630
    Abstract: Preparation of compositions of silver and CeO.sub.2 by powder metallurgy techniques overcomes problems inherent in melting silver and pure cerium and subsequently internally oxidizing the cerium in the mixture. Small concentrations of CeO.sub.2 substantially improve the electrical contact properties of silver. Silver with dispersed CeO.sub.2 is superior to silver alone for use as an electrical contact because of much greater resistance to arc erosion and welding and only slightly higher contact resistance.
    Type: Grant
    Filed: September 5, 1975
    Date of Patent: April 19, 1977
    Assignee: Engelhard Minerals & Chemicals Corporation
    Inventors: James S. Hill, Emil L. Carbone, Victor G. Mooradian, Walter G. Keyes
  • Electrical contacts of dispersion strengthened gold
    Patent number: 4018599
    Abstract: Small concentrations of certain dispersed oxides such as CeO.sub.2 substantially improve the electrical contact properties of gold. Gold with dispersed CeO.sub.2 is superior to gold for use as an electrical contact because of much greater resistance to arc erosion and welding and only slightly higher contact resistance.
