Paper Title:
Piezoelectric Properties of Perovskite-Type Lead-Free Piezoelectric Ceramics under Large Amplitude Continuous Driving
  Abstract

High-power piezoelectric characteristics of (Bi1/2Na1/2)TiO3 (BNT)- and KNbO3 (KN)-based ceramics at continuous driving were investigated. The selected compositions of BNT- and KN-based ceramics were 0.88(Bi1/2Na1/2)TiO3-0.04(Bi1/2Li1/2)TiO3-0.08(Bi1/2K1/2)TiO3 doped with 0.6 wt% MnCO3 [BNLKT4-8Mn0.6] and KNbO3-MnCO3 0.8 wt% [KN-Mn0.8] ceramics. It was found that the vibration velocity v0-P of BNLKT4-8Mn0.6 and KN-Mn0.8 ceramics linearly increased up to approximately 0.8 and 0.6 m/s, respectively. The temperature increases of BNLKT4-8Mn0.6 and KN-Mn0.8 ceramics were approximately 5°C under continuous driving at the vibration velocity of 0.6 m/s.
