Effect of PZN Addition on Piezoelectric and Ferroelectric Properties of Pb (Zr1/2Ti1/2)O3 Ceramics
Ceramics in the xPb (Zn1/3Nb2/3)O3−(1-x)Pb (Zr1/2Ti1/2)O3 [xPZN–(1-x)PZT] solid solution system are expected to display excellent dielectric, piezoelectric, and ferroelectric properties in compositions close to the morphotropic phase boundary (MPB). The dielectric behavior of ceramics with x = 0.1 − 0.5 has been characterized in order to identify the MPB compositions in this system. Combined with x-ray diffraction analysis, dielectric, piezoelectric and ferroelectric measurements, it was consistently shown that an MPB exists around x = 0.3 in this binary system. When x ≤ 0.2, the tetragonal phase dominates at ambient temperatures. In the range of x ≥ 0.4, the rhombohedral phase dominates.
