- Abstract
In this work, the 0.04Pb(Zn1/3Nb2/3)O3-0.05Pb(Mn1/3Sb2/3)O3–xPbZrO3–(0.91−x)PbTiO3 + ymol%Fe2O3 (xPZ-PZNMST + y%Fe; x = 0.440–0.460, y = 0.00–0.15) piezoelectric ceramics were synthesized by solid-state reaction method. The 0.45PZ-PZNMST + 0.10%Fe ceramic with morphotropic phase boundary shows optimum comprehensive electromechanical properties with d33 = 401 pC/N, kp=0.6, tan δ = 0.39%, Qm=921, and Tc = 314 °C. In addition, a low high-field tanδ of 0.78% at 200 V/mm is achieved in the 0.45PZ-PZNMST + 0.10%Fe ceramic. Therefore, a high vibration velocity of 0.80 m/s is obtained in 0.45PZ-PZNMST + 0.10%Fe ceramic. The maximum mechanical energy density of 0.45PZ-PZNMST + 0.10%Fe ceramic reaches 2500 J/m3, which is about four times that of commercial PZT4 ceramics (620 J/m3). The 0.45PZ-PZNMST + 0.10%Fe ceramic with good high-power performance shows a potential application in high-power ultrasonic transducers.
