不同的三元碳化物相，即Ti3AlC2，Ti3AlC，和Ti2AlC，成功地合成在一个自我维持的制度。钛、铝和碳的元素粉末之间的直接反应是强烈放热的，并且所产生的反应产物由二元碳化物组成，并且它们是部分熔融的。使用TiAl代替元素钛和铝，显著降低了燃烧温度。结果，形成三元钛铝碳化物相。此外，燃烧合成产物不烧结，易于解聚。反应条件和不同的三元相形成的自持制度的X射线衍射图案。
Different ternary carbide phases, namely Ti3AlC2, Ti3AlC, and Ti2AlC, were successfully synthesized in a self-sustaining regime. Direct reactions among elemental powders of titanium, aluminum, and carbon are strongly exothermic, and the resulting reaction products consist of binary carbides and they are partially molten. The use of TiAl, instead of elemental titanium and aluminum, significantly reduces the combustion temperature. As a result, ternary titanium aluminum carbide phases are formed. In addition, the combustion-synthesized products are not sintered and easy to deagglomerate. Reaction conditions and X-ray diffraction patterns of different ternary phases formed in a self-sustaining regime are presented.
