  • Methods of making shaped ceramic composites
    Patent number: 5358914
    Abstract: A method of producing self-supporting ceramic composite bodies of desired shape by infiltrating a permeable self-support preform with polycrystalline matrix material comprising an oxidation reaction product obtained by oxidation of a parent metal precursor, such as aluminum, and optionally containing therein metallic constituents. The composite body is formed by contacting a zone of a permeable self-supporting preform, having at least one defined surface boundary spaced from said contacting zone, with a body of molten metal which is reacted with a suitable vapor-phase oxidant to form an oxidation reaction product.
    Type: Grant
    Filed: November 9, 1992
    Date of Patent: October 25, 1994
    Assignee: Lanxide Technology Company, LP
    Inventors: Marc S. Newkirk, Shirley L. Zwicker
