Abstract

(1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3] is a relaxor ferroelectric material, which exhibits excellent piezo-, di- and ferro- (PDF) electric properties and is recognized as a smart material. Electric and optic behavior of PMN-PT is composition dependant. PMN-PT in the morphotropic phase boundary (x = 0.3 to 0.35), exhibits excellent functional response, which makes it suitable for various device applications like sensors, actuators for medical imaging, energy harvesting, and so forth. Although a large number of research reports were available on PMN-PT, the unparallel electric properties and smartness of this material could not be explored and utilized completely. Difficulty in the synthesis of pyrochlore-free ceramics and stoichiometric transfer of the material during thin-film growth were reported as two prominent reasons. This chapter presents various challenges in the synthesis of PMN-PT ceramic and discusses a novel partial covering combined with modulation and stabilization heating for the realization of device worthy PMN-PT ceramic pellets for laser ablation. Columbite B-site precursor method is used for the synthesis of 0.65 PMN-0.35 PT ceramic and pulsed laser deposition is used for thin-film growth. © 2022 Elsevier Inc. All rights reserved.
