A layered ternary carbide Ti3AlC2 was synthesized by pressureless calcining process from the mixture of titanium, aluminum and graphite powders. Almost single-phase Ti3AlC2 was obtained after calcining at 1400°C for 4 h. The microstructural evolution during the formation of Ti3AlC2 was examined at the temperature from 900°C to 1400°C. Ti3AlC2 was formed through an intermediate carbide of Ti3AlC, which was seldom reported in previous literatures. Based on the results of X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS), a possible reaction mechanism was proposed to explain the formation of Ti3AlC2.
