AbstractVarious material parameters for hot pressed ceramics in the solid solution system (x) PbZrO3- (y) Pb(Zn1/3Nb2/3)O3- (z) PbTiO3(PZNT) have been studied. Previous work within this system has shown a morphotropic phase boundary separating the antiferroelectric (Aα) and the high temperature rhombohedral (Fα) phases. This paper will further explore the electrical field dependence of the complex elastic constants (s'11Eand s”11E), complex piezoelectric coefficients (d'31and d”31), and dielectric constant (K33) near this phase boundary. In addition, these parameters will be compared to those obtained for PZT-5A at room temperature. |
