摘要：
A composite ceramic sintered body is made from a ceramic matrix comprised mainly of silicon nitride, silicon oxynitride or an inorganic oxide selected from alumina, mullite, zirconia, high silica glass, lithium-aluminosilicate glass, magnesium-aluminosilicate glass or barium-magnesium-aluminosilicate glass, containing both whiskers and particles of a material selected from silicon carbide, silicon nitride, silicon oxynitride, alumina and zirconia dispersed therein. The whiskers have a diameter of 0.1 to 5 µm and the particles have an average particle size of 5 to 60 µm. The composite ceramic sintered body is homogeneous and isotropic, and it has a high strength and high toughness at a high temperature and an excellent heat resistance and oxidation resistance.
