Abstract

A complete set of elastic, piezoelectric, and dielectric constants of [011]c poled multidomain 0.24Pb(In1/2Nb 1/2)O3-0.46Pb(Mg1/3Nb2/3)O 3-0.30PbTiO3 ternary single crystal has been determined using resonance and ultrasonic methods and the temperature dependence of the dielectric permittivity has been measured at 3 different frequencies. The experimental results revealed that this [011]c poled ternary single crystal has very large transverse piezoelectric coefficient d32 = - 1693 pC/N, transverse dielectric constant ε110 ∼ 7400 and a high electromechanical coupling factor k32 ∼ 90%. In addition, its coercive field is 2 times of that of the corresponding binary 0.69Pb(Mg1/3Nb2/3)O3-0.31PbTiO 3 single system with much better temperature stability. Therefore, the crystal is an excellent candidate for transverse mode electromechanical devices.
