Pb(Mg_(1/3)Nb_(2/3))O_(3)-induced oxygen octahedral distortions and domain growth for concurrent enhancement of multiple parameters in PNN-PZTOA
Enhancing key parameters such as the piezoelectric coefficient(d33),Curie temperature(TC),electromechanical coupling coefficient(kp),and dielectric loss(tanδ)is crucial for improving the overall performance of piezoelectric ceramics.However,the trade-off relationships among these parameters represent a significant challenge in this field.To address this issue,we propose a synergistic strategy that leverages atomic radius differences(Mg^(2+)and Pb(Mg_(1/3)Nb_(2/3))O_(3))to induce lattice distortion and promote ferroelectric domain growth.This approach successfully achieves the simultaneous enhancement of multiple parameters in the Pb(Ni_(1/3)Nb_(2/3))O_(3)-PbZrO_(3)-PbTiO_(3)system,resulting in excellent overall performance with d33=681 pC/N,inverse piezoelectric coefficient d_(33)^(*)=953 pm/V,TC=213℃,kp=0.69,and tanδ=1.47%.Rietveld refinement,Rayleigh analysis,and piezoresponse force microscopy(PFM)characterization confirm that the cooperative modulation of lattice distortion and domain growth is key to performance improvement.Additionally,the material demonstrates excellent thermal stability and high-temperature dielectric breakdown strength.This study provides a simple and effective strategy to overcome the antagonistic relationships among multiple parameters in piezoelectric ceramics.
