Studies on structural, electrical and electromechanical properties of Sb3+-modified PLZT

The Sb-modified PLZT with a general formula [Pb0.92(La1−zSbz)0.08(Zr0.65Ti0.35)0.98]O3 (z = 0.0, 0.3, 0.6, 0.9, 1) were prepared by a solid-state reaction technique. Detailed studies of the effect of Sb in small concentration on structure, microstructure, electrical as well as electromechanical properties of the PLZT ceramics have been completed. Preliminary X-ray diffraction study of the materials suggested the formation of single-phase compound. SEM studies reveal the presence of homogeneous grain with a certain degree of porosity. The electrical and electromechanical properties of the compounds have provided their interesting ferroelectric and sensing properties.
