Piezoelectric shear-mode properties of Pb(Yb1/2Nb1/2)O3-PbTiO3 ceramics

Journal Article


Abstract


  • A Pb(Yb1/2Nb1/2)O3-PbTiO3 [PYNT] solid solution was synthesized and characterized for its potential use. The shear-mode dielectric and piezoelectric behaviors of PYNT with a morphotropic phase boundary (MPB) composition were studied as a function of temperature. Dielectric permittivity K11T and loss were found to be 2310 and 2.5%, respectively, at room temperature. Piezoelectric coefficient d15 and electromechanical coupling factor k15 were calculated to be 710 pC/N and 0.70, respectively, maintaining nearly constant up to 300 ��C, resistivity and RC time constant were observed to be 2.4 �� 109 �� cm and 1.07 s, respectively, at 350 ��C. These good piezoelectric properties, together with the high Curie temperature (Tc ��� 370 ��C), indicate that PYNT is a promising candidate for high temperature-shear sensor and inkjet actuator applications. �� 2010 Elsevier B.V.
