Abstract

PbTiNb2O8 is a new piezoelectric ceramic that satisfy applications of energy harvesters. Complex structure change and dipole relaxation of Pb-site doping PbTiNb2O8 piezoelectric ceramics were investigated. The synchrotron radiation study results show that with 5mol% divalent cation substitution to Pb-site brings the various structure changes. Zn and Ni doping bring the centrosymmetry secondary phase, and affect the performance greatly. The dielectric spectroscopy of polarized and unpolarized samples in the frequency range of 50Hz~100MHz were studied. The dipole relaxation of Pb0.95M0.05TiNb2O8 ceramics occurred at around 107Hz, and the dipole resonant frequency (the first highest peak of spectroscopy) of polarized sample is lower than the unpolarized sample.
