Piezoelectric Characteristics

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)TiO3doped with 0.6 wt% MnCO3[BNLKT4-8Mn0.6] and KNbO3-MnCO30.8 wt% [KN-Mn0.8] ceramics. It was found that the vibration velocityv0-Pof 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.

Dielectric And Piezoelectric Properties

Lead-free (1-x-y)Na1/2Bi1/2TiO3-xBaTiO3-yBiFeO3 ceramics were synthesized by ordinary sintering technique. The compositional dependence of phase structure and electrical properties of the ceramics was systematically investigated. All samples possessed pure perovskite structure. The dielectric and piezoelectric properties of ceramics were investigated with the amount of different BiFeO3 substitutions. The addition of BiFeO3 can not only decrease Ec and Pr but also lead to a significant degradation of the dielectric loss tanδ.
