Electromechanical characterization of Pb(In0.5Nb0.5)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 crystals as a function of crystallographic orientation and temperature

Abstract

PbTiO 3 ternary single crystals ͑PIN-PMN-PT͒ were reported to have broader temperature usage range ͑T R-T ͒ and comparable piezoelectric properties to Pb͑Mg 1/3 Nb 2/3 ͒O 3 -PbTiO 3 ͑PMNT͒ crystals. In this work, the orientation dependent dielectric, piezoelectric and electromechanical properties for PIN-PMN-PT crystals were investigated along ͗001͘ and ͗110͘ directions. The electromechanical couplings k 33 and k 32 for ͗110͘ poled crystals were found to be 0.91 and 0.91, respectively, with piezoelectric coefficients d 33 and d 32 on the order of 925 and Ϫ1420 pC/N. Of particular significance was the mechanical quality factor Q 33 for ͗110͘ oriented crystals, which was found to be Ն500, much higher than the Q values of ͗001͘ oriented relaxor-PT crystals ͑Q ϳ 70-200͒. The temperature dependence of the piezoelectric properties exhibited good temperature stability up to their ferroelectric phase transition T R-T ϳ 125°C, indicating ͗001͘ and ͗110͘ oriented PIN-PMN-PT are promising materials for transducer applications, with the latter for high power resonant devices where low loss ͑high Q͒ was required.

The temperature dependence of the dielectric properties has been measured for both PMN-0.…”

Phase transition behaviors in relaxor ferroelectric [001]-poled Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 single crystals studied by Brillouin light scattering and dielectric spectroscopies

“…Recently, various properties of PIN-PMN-PT single crystals near MPB including elastic, dielectric, and piezoelectric properties have been studied under different poling conditions. [9][10][11][12][13][14][15][16][17][18][19][20][21] However, the ferroelectric phase transition behaviors of PIN-PMN-PT single crystals have not been studied in detail. A great portion of the published data on this system are reported on poled samples at room temperatures, and studies on the phase transition behaviors in the temperature window of as-grown or unpoled samples in comparison with poled ones are scarce.…”

Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 Piezoelectric Single-Crystal Rectangular Beams: Mode-Coupling Effect and Its Application to Ultrasonic Array Transducers

“…Among them, binary relaxor-based Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PMN-PT) single crystals are regarded as one of the most representative types and have received much interest in ultrasonic transducer applications over the past two decades [6][7][8]. More recently, ternary relaxor-based Pb(In 1/2 Nb 1/2 )O 3 -Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PIN-PMN-PT) single crystals, especially for those with the PIN:PMN:PT ratio of 0.33:0.35:0.32, have been synthesized and evaluated to show similarly strong piezoelectric properties as well as significantly higher MPB temperature, Curie temperature, and coercive field when compared with the PMN-PT single crystals [9][10][11][12][13].…”
