Abstract: High purity and bulk Ta2AlC ceramics had been synthesized by self-propagating high-temperature synthesis, pressure-less sintering and spark plasma sintering, using Ta, Al and carbon black powders as raw materials. Microstructures and properties of the as-fabricated Ta2AlC ceramics were investigated. The Vickers hardness, flexural strength and fracture toughness of the as-fabricated bulk Ta2AlC ceramics are 5.6 GPa, 510 MPa and 6.16 MPa·m1/2, respectively. The fast heating rate, short sintering time and fine grain formation in the spark plasma sintering resulted in a fine-grain strengthening effect which led to the high hardness and strength. The Ta2AlC ceramics oxidized at the temperature range of 700—900 ℃ showed a linear oxidation kinetics trend. When the Ta2AlC ceramic was oxidized at 700 ℃ for 15 h, the oxidation layer of the Ta2AlC was mainly composed of Ta2O5. And the oxidation products would become Ta2O5 and AlTaO4 while the oxidation temperature was risen up to 800—900 ℃.
