  • Patent number: 6573210
    Abstract: A composite ceramic-metal material has an Al2O3 matrix interpenetrated by a network of a ductile metal phase with a higher meltin temperature than aluminum and which makes up 15 to 80 vol. % of its total volume. The Al2O3 matrix forms a coherent network that makes up 20 to 85 vol. %, and the material contains 0.1 to 20 atom % aluminide. To produce this composite material, a green body shaped by powder metallurgy and which contains a finely divided powdery mixture of Al2O3 and optionally other ceramic substances, as well as one or several metals or metal alloys different from aluminum and to which 0.1 to 20 atom % aluminum are added, in relation to the metal proportion, is sintered. The composition is selected in such a way that maximum 15 vol. % aluminide phase can be formed in the finished sintered body.
