High Performance Relaxor-Based Ferroelectric Single Crystals for Ultrasonic Transducer Applications
Relaxor-based ferroelectric single crystals Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) have drawn much attention in the ferroelectric field because of their excellent piezoelectric properties and high electromechanical coupling coefficients (d33~2000 pC/N, kt~60%) near the morphotropic phase boundary (MPB). Ternary Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (PIN-PMN-PT) single crystals also possess outstan...

متن کاملEffects of Li2O and Na2O Addition on Growth and Electrical Properties of PbTiO3 Single Crystals
parent red-brown and brown single crystals, respec tively, and had average size of 3.0•~2.8•~1.1mm and 3.6•~2.8•~1.0mm. (3) The content of Li2O in all the Li doped crystals was less than 0.01wt%, whereas the Na2O content was more than 0.07wt% and increased with increasing addition of Na2O. (4) Crystals doped with Li2O showed no variations in the lattice constant, but the lattice constant of c-a...
