This study aims to enhance the performance of Pb(Mg1/3Nb2/3)O3-Pb(Al1/2Nb1/2)O3-Pb(Zr0.52Ti0.48)O₃ (PMN-PAN-PZT) piezoelectric ceramics by investigating the effects of varying PAN and PMN content and adding Nb₂O？ on their piezoelectric properties. The results show that with 2 mol% of PMN and PAN, the morphotropic phase boundary (MPB) region exhibits the highest piezoelectric properties. Additionally, excess Nb₂O？ positively influenced the piezoelectric properties, maximizing electro-mechanical coupling factor (k？=63%, d33=440 pC/N). These findings contribute to developing next-generation high-performance piezoelectric materials, with potential for improved efficiency and performance in various industries.
