Abstract: Ti₃SiC₂ materials have been fabricated by spark plasma sintering of the elemental powders with the addition of Al. At the heating rate of 80℃/min and under the pressure of 30MPa, the ideal synthesis temperature of Ti₃SiC₂ is in the range of 1150-1250℃. The addition of Al is in favor of the formation of Ti₃SiC₂. The synthesized compound has the molecular of Ti₃Si_0.8Al_0.2C₂ and lattice parameters of a=0.3069nm, c=1.7670nm. Its grain is plane-shape with a size of about 50μm in the elongated dimension. The prepared material has Vickers hardness of 3.5-5.5GPa(at 1N and 15s) and is as readily machinable as graphite’s.
