The ternary carbide is a kind of compound comprising covalent, metallic and ionic bonds in one crystal cell, which results in unusual properties combining the merits of both metals and ceramics. Normally, the fabrication of Ti3AlC2 ceramic parts needs very rigorous conditions. Moreover, all the fabrication approaches already used start from Al4C3 as aluminum source for the purpose of avoiding Al lost during the synthesizing/sintering process. The single-phase ternary carbide of Ti3AlC2 was combustion synthesized by using Ti, Al and C powders as the raw materials in the present work. The experimental results show that the phase formation of the final product is affected by the addition of TiC and Ti3AlC2 exceptionally. The amount of Ti3AlC2 is enhanced with increasing the addition of TiC and Ti3AlC2 in the raw mixtures and decreasing the combustion temperatures
