Being capable of interconverting electrical and mechanical energy, piezoelectric materials are essential for electromechanical devices. In this study, high-performance 0.95Pb(Zr 0.52 Ti 0.48 )O 3 –0.05Pb(Mn 1/3 Nb 2/3 )O 3 (PZT-PMnN) piezoelectric ceramics were prepared by spark plasma sintering (SPS). We systematically investigated temperature-dependent electrical properties and phase structure of ceramics. The SPS temperature was found to be optimized at 950 °C. PZT-PMnN ceramic sintered at 950 °C possessed high piezoelectric performances, i.e. d 33 of 411 pC/N and d 33 * of 556 pm/V. Furthermore, a high mechanical quality factor Q m (480) and low dielectric loss (0.19%) were obtained. Therefore, the spark-plasma-sintered PZT-PMnN ceramic is a promising candidate for applications.
