| dc.description.abstract | Ceramics in the xPb(Zn<inf>1/3</inf>Nb<inf>2/3</inf>)O <inf>3</inf>-(1-x) Pb(Zr<inf>0.5</inf>Ti<inf>0.5</inf>)O<inf>3</inf> [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 = 0.1-0.6 has been characterized in order to identify the MPB compositions in this system. Combined with X-ray diffraction results, ferroelectric hysteresis measurements, and Raman reflectivity analysis, it was consistently shown that an MPB exists between x = 0.2 and x = 0.3 in this binary system. When x ≤ 0.2, the tetragonal phase dominates at ambient temperatures. In the range of x ≥ 0.3, the rhombohedral phase dominates. For this rhombohedral phase, electrical measurements reveal a profound frequency dispersion in the dielectric response when x ≥ 0.6, suggesting a transition from normal ferroelectric to relaxor ferroelectric between 0.5 ≥ x ≤ 0.6. Excellent piezoelectric properties were found in 0.3PZN-0.7PZT, the composition closest to the MPB with a rhombohedral structure. The results are summarized in a PZN-PZT binary phase diagram. © Springer Science + Business Media, Inc. 2006. | |
