High piezoelectric performance and temperature dependence of ferroelectric and piezoelectric properties of Bi(Mg0.5Zr0.5)O3–PbTiO3 near morphotropic phase boundary
According to consideration on the average radius of B-site cation of BiMeO3, we reported that the Bi(Mg0.5Zr0.5)O3–xPbTiO3 compound at the morphotropic phase boundary (MPB) of x=0.58 possesses a piezoelectric coefficient d33 as high as 306 pC/N. The optimal piezoelectric and ferroelectric properties near the MPB might be attributed to its lower lattice distortion, as described by change of FWHM value for {1 1 1}PC peaks. Furthermore, Bi(Mg0.5Zr0.5)O3–xPbTiO3 displayed stable ferroelectric and piezoelectric properties over a temperature range from ambient temperature to above 160 °C, as exhibited by temperature dependence polarization and strain versus electric field curves and thermal depoling process.
