摘要：

The electric and mechanical properties of PMN-PT (67/33) ferroelectric relaxor crystal were measured. The piezoelectric and dielectric properties of PMN-PT crystal was discussed in comparison with the generally used piezoelectric ceramics and polymer. The performances of the unturned PMN-PT ultrasonic transducer with longitudinal vibration mode was evaluated. The influence of the PMN-PT dielectric and mechanical loss on impedance and transducer loss were discussed.
