摘要

The morphotropic phase boundary (MPB) for high-density solid solutions with compositions of xPb(Mn_(1/3)Nb_(2/3))O_(3-y)PbZrO_3-zPbTiO_3 (PMnNZT) with x = 0.02-0.16, y = 0.42-0.56, and z = 0.42-0.56 has been refined on the basis of an analysis of the dielectric and piezoelectric properties of the fabricated samples. An X-ray diffraction analysis of the PMnNZT solid solutions suggested that the refined rhombohedral-tetragonal MPB in this material system is in the compositional region x = 0.02-0.134, y =0.42-0.54, and z = 0.44-0.485. It was found that a hard-mode solid solution with x = 0.10, y = 0.45, and z = 0.45, which lies in the refined MPB region, exhibited excellent piezo- and ferroelectric properties highlighting its potential as a high-power piezoelectric material for ultrasonic vibrators and piezoelectric transformers.
