  • Molybdenum disilicide alloy matrix composite
    Patent number: 5069841
    Abstract: Compositions of matter consisting of matrix materials having silicon carbide dispersed throughout them and methods of making the compositions. A matrix material is an alloy of an intermetallic compound, molybdenum disilicide, and at least one secondary component which is a refractory silicide. The silicon carbide dispersant may be in the form of VLS whiskers, VS whiskers, or submicron powder or a mixture of these forms.
    Type: Grant
    Filed: August 9, 1990
    Date of Patent: December 3, 1991
    Assignee: University of California
    Inventors: John J. Petrovic, Richard E. Honnell, W. Scott Gibbs
  • Silicon nitride reinforced with molybdenum disilicide
    Patent number: 5064789
    Abstract: Compositions of matter comprised of silicon nitride and molybdenum disilicide and methods of making the compositions, where the molybdenum disilicide is present in amounts ranging from about 5 to about 50 vol. %.
    Type: Grant
    Filed: September 27, 1990
    Date of Patent: November 12, 1991
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: John J. Petrovic, Richard E. Honnell
  • Zirconia-molybdenum disilicide composites
    Patent number: 5063182
    Abstract: Compositions of matter comprised of molybdenum disilicide and zirconium oxide in one of three forms: pure, partially stabilized, or fully stabilized and methods of making the compositions. The stabilized zirconia is crystallographically stabilized by mixing it with yttrium oxide, calcium oxide, cerium oxide, or magnesium oxide and it may be partially stabilized or fully stabilized depending on the amount of stabilizing agent in the mixture.
