Abstract: | The dielectric constant (εr), dielectric loss (tan δ) and strain induced by electric field in lead magnesium niobate–lead titanate (PMN-PT/PMNT) solid solutions in the morphotropic phase boundary (MPB) region at different sintering temperatures have been studied. εr and tan δ increase, whereas Curie phase transition range decreases with the increase in sintering temperature. Strain levels in the range of 0.07–0.2% were obtained. A high saturated strain% 0.19, a high d33 coefficient 320 pm/V and a low strain hysteresis% 3.5 in PMNT 68/32 composition sintered at 1200 °C indicate its suitability for actuator applications. |
