Abstract: A process for producing a ceramic-metal composite, includes (1) mixing TiO2, and optionally Ti, with at least one of a boron-containing or carbon-containing material to give a green body mix; (2) heat treating the green body mix to a temperature from 900° C. to 1900° C. and below a temperature which leads to an autocatalytic reaction; (3) carrying out an exchange reaction between the material and the TiO2 to give a reaction product comprising at least one of TiBx and TiCy, wherein 0≦x 23 2 and 0≦y≦1; (4) producing a porous green body from the reaction product; (5) filling the porous green body with liquid aluminum after the exchange reaction; and (6) carrying out a reaction between the reaction product in the green body and the aluminum to form the ceramic-metal composite comprising a ceramic phase selected from the group consisting of TiBx-, TiCy-, TiCN- and Al2O3 and a comprising a metallic phase comprising an intermetallic compound of Ti and Al.
