| Abstract | Dense bulk Ta2AlC ceramic was fabricated by in-situ reaction/hot pressing of Ta, Al and C powders. The reaction path and effects of initial composition on the purity were investigated. It was found that Ta2AlC formed through the reactions between AlTa2 and graphite, or between Ta5Al3C, TaC and graphite at 1500-1550 degrees C. By modifying the molar ratio of the initial Ta, Al, and C powders, single-phase Ta2AlC was prepared at 1550 degrees C under an Ar atmosphere with an optimized composition of Ta: Al: C = 2: 1.2: 0.9. The lattice parameter and a new set of X-ray diffraction data of Ta2AlC were obtained. In addition, Ta2AlC was reported unstable above 1600 degrees C and decomposed to Ta4AlC3, and then to TaCx. |
