  • Ceramic articles containing silicon carbide
    Patent number: 4883779
    Abstract: A shaped article comprises a ceramic matrix and dispersed therein in the range of 5 to 30 weight percent mechanically added silicon carbide, said article having a modulus of elasticity (E) value of at least 10 percent greater than the inherent elastic modulus value of the fully dense host matrix. The articles are useful as high temperature stable reinforcement materials in composites requiring a high modulus of elasticity.
    Type: Grant
    Filed: October 20, 1988
    Date of Patent: November 28, 1989
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Jerome W. McAllister, Lien-Huong T. Pham, Harold G. Sowman
