  • Ceramic composites with improved thermal shock resistance
    Patent number: 5208193
    Abstract: A high density, shock resistant ceramic comprising from 1 to about 4 mols of a a dense spinel ceramic matrix having dispersed therein, 1.5 to 1, respectively, of a metal oxide derived from a decomposable salt of said metal and having a thermal expansion characteristic different from said dense spinel ceramic matrix and at the decomposition temperature a volume less than that exhibited by its salt form and a process for preparing same.
    Type: Grant
    Filed: March 7, 1989
    Date of Patent: May 4, 1993
    Assignee: The Dow Chemical Company
    Inventors: Ronald R. Smyth, Walter W. Henslee
