摘要: A ternary relaxor ferroelectric single crystal Pb (In1/2Nb1/2) O3–Pb (Mg1/3Nb2/3) O3–PbTiO3 was grown by the modified Bridgman method. The real compositions, phase structures and performances of different regions in the boule were characterized. The real composition deviated from the nominal composition, but the In/Pb ratio in the crystal remained nearly a constant. The piezoelectric coefficient d33, electromechanical coupling factor k33 and coercive field Ec after〈 011〉 poling can reach up to 1500pC/N, 0.90 and …
