The ceramic composites were prepared from elemental powders, i.e., titanium powders, aluminum powders and graphite powders. The powder mixtures, with a composition Ti<SUB>50</SUB>Al<SUB>25</SUB>C<SUB>25</SUB> (in atomic% ) were cold pressed, and combustion reaction was carried out to form ceramic composites in Ti-Al-C system. However, the reaction products had extensive pores. Then the products densified by hot pressing for 1.8ks at 1473K under 70MPa in Ar gas atmosphere. It was found that the matrix phase (Ti<SUB>2</SUB>AlC) had good properties, e.g., microhardness and thermal expansion coefficient, as a composite phase for TiAl alloys. The processing technique in the present investigation is of interest as a new combustion reaction process to synthesize in-situ ceramics and ceramic composites.
