N2 - In this study, the Pb(Yb1/2Nb1/2)O3 (PYN) relaxor with high Curie temperature (TC ∼300 °C) was incorporated into PbZrO3-PbTiO3 (PZ-PT) ceramics to form 0.1PYN-(1-x)PZ-xPT ternary ceramics, and their phase compositions were systematically investigated, providing the more detailed phase diagrams, dielectric, piezoelectric, and ferroelectric properties. Excellent piezoelectric performance (d33 ∼ 450 pC/N, d33* ∼714 pm/V), with high coercive field (EC ∼17.5 kV/cm) and TC (∼398 °C) were simultaneously achieved in the 0.1PYN-0.41PZ-0.49PT composition near the morphotropic phase boundary (MPB). The value of d33 × EC, which exhibits higher than commercial PZT ceramics, indicates its suitability for high-field excitation devices. Additionally, the temperature stability of the resonant frequency (fr) is qualitatively studied by analyzing the main factors influencing fr from a theoretical perspective. Superior stability is achieved in the 0.1PYN-0.38PZ-0.52PT composition (TC ∼ 405 °C) with tetragonal phase, and the temperature coefficient of resonant frequency (Δfr /fr 25 °C) remains within 0.5% up to 300 °C, far outperformance than previous reports.
