Characterization of high TC Pb (Mg1/3Nb 2/3)O3 - PbZrO3 - PbTiO3 single crystals fabricated by solid state crystal growth

Journal Article


Abstract


  • Ferroelectric crystals near the morphotropic phase boundary (MPB) in the Pb (Mg13 Nb23) O3 -PbZr O3 -PbTi O3 ternary system were grown using the solid state crystal growth technique. A MPB composition with a Curie temperature of ���205 ��C was selected for characterization of the piezoelectric properties and temperature dependent behavior. The room temperature electromechanical coupling factors were found to be 90% for k33 and ���-87% for k32, respectively, comparable to Pb (Mg13 Nb23) O3 -PbTi O3 (PMN-PT) crystals. The coercive field, being on the order of 5 kVcm, was found to be nearly double that of the pure PMN-PT. The temperature dependence of the piezoelectric and electromechanical properties showed temperature stability up to 160 ��C, expanding the temperature usage range for actuator and ultrasonic transducer applications. �� 2007 American Institute of Physics.
