Abstract :
In this study, ceramic samples with composition 0.675Pb(Mg⅓Nb⅔)O3–0.325PbTiO3 were tested and assessed in terms of piezoelectric applications. This material showed relaxor ferroelectric behavior at temperatures around the ferro-paraelectric phase transition. In this temperature region, the material also had a high real dielectric permittivity, which fell slightly with the application of an electric field between 0 and 1 kV/mm. Consequently, high effective piezoelectric coefficients were observed for this material, which were found to be almost linearly tunable with electric fields between 1 and 3 kV/mm. Hence, the material studied here appears to be a promising candidate for the manufacture of certain piezoelectric devices.
