Dielectric, elastic and piezoelectric losses are investigated in soft Pb(Zr,Ti)O3-based piezoelectric ceramics in terms of polarization direction dependence of the properties. The difference of the mechanical quality factor at the resonance and anti-resonance frequencies were obtained by the impedance method. The polarization angle of the samples varied from 0 (E//PS) to 90 degree (E⊥PS) for “effective” k31 and k33 vibrating modes. The change in the piezoelectric losses is dominant in comparison to the dielectric or elastic losses in both vibration modes.
