Abstract

Phase transitions in PLZT 2/92/8 ceramics were investigated by X-ray, dielectric, pyroelectric and Raman scattering measurements. The antiferroelectric-ferroelectric-paraelectric phase sequence in this material was confirmed. The antiferroelectric and ferroelectric phases coexist in an exceptionally wide low-temperature range. Possible reasons for the differentiation in properties of the ferroelectric phase in the high- and low-temperature ranges are discussed.
