Abstract

This study highlights the optimization of Mn-doped (1-x)Pb(Mg_2/3Nb_1/3O₃-xPbTiO₃ (PMN-PT) ceramics for high-power piezoelectric applications through a combination of (001) grain texturing with BaTiO₃ seed and oxygen atmosphere sintering. The synergistic effects of Mn-induced domain-pinning and grain alignment significantly improved both the soft and hard piezoelectric properties. Optimized ceramics achieved a piezoelectric coefficient (d₃₃) of 455 pC/N and a mechanical quality factor (Q_m) of 1466, demonstrating high-performance potential. Oxygen sintering reduced porosity, further boosting mechanical stability and piezoelectric response. High-power performance tests confirmed these advancements, achieving a maximum vibration velocity of 0.45 m/s. This study underscores the potential of combining texturing and defect control to develop high-performance piezoelectric materials tailored for advanced applications in high-frequency and high-power devices.
