A consolidated metal-ceramic composite comprises a first phase of particles of aluminum oxide or a solid solution based on aluminum oxide uniformly distributed in a second matrix phase wherein the second matrix phase is non-reactive with aluminum oxide and contains a sufficient amount of titanium carbide at the interface between the first and second phase to prevent a chemical reaction at the interface during consolidation at the liquidus temperature and which exhibits good mechanical properties with regard to strength and toughness at high temperatures up to about 1200.degree.
