The piezoelectricity of PZT is particularly connected with its unique crystal structure, because of the presence of the so-called morphotropic phase boundary (MPB) (Jaffe et al., 1954). The MPB (0.48 ≤ x ≤ 0.50 at room temperature) separates a Zr-rich rhombohedral (R) phase and a Ti-rich tetragonal (T) phase.

May 13, 2019 · We report on the correlated investigation between macroscopic piezoelectric properties and the microscopic deformation of crystal structures of both epitaxial and polycrystalline Pb (Zr,Ti)O 3...

Apr 23, 2021 · As the properties of PZT ceramics are very much sensitive near the morphotropic phase boundary (MPB) separating the ferroelectric tetragonal (FT) and ferroelectric rhombohedral (FR) phases due to spontaneous polarisation in different directions over a wide range of temperature in the phase diagram [2, 3], PZT materials can be used in various ...

MPB based PZT ceramics and its compositionally modified variants with soft and hard dopants have been exploited in many sensor and transducer applications for their high electromechanical properties [6, 7].

Apr 1, 2000 · The perovskitelike ferroelectric system PbZr 1 − x Ti x O 3 (PZT) has a nearly vertical morphotropic phase boundary (MPB) around x = 0.45 – 0.50. Recent synchrotron x-ray powder diffraction measurements by Noheda et al. [Appl. Phys. Lett. 74 , 2059 (1999)] have revealed a monoclinic phase between the previously established tetragonal and ...
