N2 - For high-power applications, piezoelectric materials are required to balance high vibration velocity ( v 0), high mechanical quality factor ( Q m), large piezoelectric constant ( d 33), and high Curie temperature ( T C), which is challenging due to inherent trade-offs. This study investigates the effects of phase structure on the electrical properties, temperature stability, and high-power characteristics of 0.04Pb(Yb1/2Nb1/2)O3-0.06Pb(Mn1/3Nb2/3)O3- x PbTiO3-(0.9- x )PbZrO3 (PYN-PMnN-PZT, x = 0.42 ∼ 0.52) ceramics by adjusting the Zr/Ti ratio in detail. The results show that the composition near the morphotropic phase boundary (MPB, x = 0.48) exhibits optimal comprehensive properties: d 33 (295 pC/N), k p (0.59), ε r (1150), tanδ (0.40 %), T C (352 °C), and Q m (1115 in 31-mode, 2012 in p-mode). This composition also demonstrates excellent temperature stability, with the temperature coefficient of resonant frequency (Δ f r/ f r,25°C) remaining within 1 % below 300 °C. In high-power applications, these ceramics achieve impressively high maximum vibration velocities (>1 m/s) at Δ T = 20 °C across a broad compositional range ( x from 0.42 to 0.52), which are higher than those of commercial hard PZT ceramics, suggesting that the PYN-PMnN-PZT ceramic is a competitive and potential candidate for high-power applications.
