Sinterable Ti3SiC2powder was synthesized from a powder mixture with a molar ratio of 1.0Ti:0.3Al:1.2Si:2.0TiC by heating at 1200°C in Ar flow. Almost single-phase peaks of Ti3SiC2were observed in X-ray diffraction patterns. The powder was dispersed in ethanol using polyethylenimine (PEI) as the polymer dispersant. Textured dense Ti3SiC2ceramics were successfully fabricated by slip casting in a strong magnetic field followed by pressureless sintering at 1400°C for 2h. The relative density of these Ti3SiC2ceramics was 99.4%, and the bending strength, fracture toughness and electrical resistivity were 623 ± 9MPa, 5.9 ± 0.1 MPa·m1/2and 0.31 μΩ·m, respectively. Compared with those of nontextured pressureless sintered samples of almost full density, the bending strength and fracture toughness of the textured Ti3SiC2ceramics were increased by factors of 1.6 and 1.4, respectively.
