The 1.0 mol% CuO-added 0.14Pb(Mn1/3Nb2/3)O3-0.86Pb(Zr0.55Ti0.45)O3 (CPMnN-PZT) piezoceramics were synthesized at low temperatures (≤ 950 °C) by the columbite method to remove the pyrochlore phase. It exhibited a high Qm of 3016 and a high TC of 309 °C. However, it showed small d33 and kp values of 143 pC/N and 0.43, respectively. The CPMnN-PZT piezoceramic was textured along the  direction using BaTiO3 (BT) templates to enhance its soft piezoelectric properties. The -textured CPMnN-PZT + y vol% BT piezoceramics (1.0 ≤ y ≤ 5.0) were densified at a low temperature of 950 °C with a high Lotgering factor (≥ 92%). The textured sample (y = 1.0) showed a high Qm of 1400 with increased d33 and kp values of 278 pC/N and 0.58, respectively, and its piezoelectricity showed excellent temperature stability up to 225 °C. Therefore, the textured CPMnN-PZT sample can be used for developing high-power piezoelectric devices.
