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 Ω 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.
