Abstract
The enhanced high-power performance of 0.93 Pb(Zr1-xTix)O3-0.05 Pb(Mn1/3Sb2/3)O3-0.02 Pb(Sc1/2Nb1/2)O3 (x = 0.48, 0.50, 0.52, 0.54, 0.56) piezoelectric ceramics (PZT-PMS-PSN) has been achieved with notable improvement in the piezoelectric coefficient (d33). The presence of the monoclinic phase (Cc) has led to an increase in d33 from 214 pC N−1 to 315 pC N−1. Therefore, the composition 0.93 Pb(Zr0.48Ti0.52)O3-0.05 Pb(Mn1/3Sb2/3)O3-0.02 Pb(Sc1/2Nb1/2)O3 exhibits excellent mechanical and electrical parameters: a d33 value of 315 pC N−1, a high mechanical quality factor of 1578, an electromechanical coupling factor kp of 52 %, and a low dielectric loss tanδ of only 0.288 %. Additionally, this ceramic exhibits a significantly high Curie temperature (Tc), reaching up to 328 °C which stabilizes its ferroelectric phase. Moreover, the phase transition of PZT-PMS-PSN ceramics from rhombohedral to tetragonal phase was investigated by X-ray diffraction, Raman scattering, Piezo-response force microscopy.
