N2 - Al-doped Ti3SiC2 ceramics were prepared by hot-pressing sintering, and the phase composition, microstructure, oxidation resistance and microwave dielectric properties of the prepared samples were characterized by X-ray diffractometer, scanning electron microscope, energy dispersive spectroscopy and vector network analyzer, respectively. Results show that the prepared ceramic with Al doping has higher mass fraction of Ti3SiC2, and the as-prepared ceramic grains present a typical laminated appearance. Through the Al doping approach, the oxidation resistance of Ti3SiC2 ceramic at 1200℃ is significantly improved, and its real component ε' and imaginary component ε″ of permittivity are greatly increased, which are 60.8 and 6.28 in average in the frequency range of 8.2~12.4 GHz, respectively.
