摘要	Ti/TiSi2/TiC powder mixtures with molar ratios of 1:1:4 (M1) and 1:1:3 (M2) were first employed for the synthesis of Ti3SiC2 through pulse discharge sintering (PDS) technique in a temperature range of 1100-1325 degreesC. It was found that Ti3SiC2 phase began to form at the temperature above 1200 degreesC and its purity did not show obvious dependence on the sintering temperature at 1225-1325 degreesC. The TiC contents in M2 samples is always lower than that of the M1 samples, and the lowest TiC contents in the M1 and M2 samples were calculated to be about 7 wt% and 5 wt% when the sintering was conducted at the temperature near 1300 C for 15 minutes. The relative density of the M1 samples is always higher than 99% at sintering temperature above 1225 C, indicating a good densification effect produced by the PDS technique. A solid-liquid reaction mechanism between Ti-Si liquid phase and TiC particles was proposed to explain the rapid formation of Ti3SiC2. Furthermore, it is suggested that Ti/TiSi2/TiC powder can be regarded as a new mixture to fabricate ternary carbide Ti3SiC2.
