Journal ArticleDOI
The perovskite structure—a review of its role in ceramic science and technology
TL;DR: In this paper, the perovskite structure is used to illustrate the relationship of structure to composition, and the history of the fundamental science of structure-to-composition is described.
Journal ArticleDOI
Origin of the high piezoelectric response in PbZr1-xTixO3
TL;DR: High resolution x-ray powder diffraction measurements on poled PbZr1-xTixO3 (PZT) ceramic samples have shown that for both rhombohedral and tetragonal compositions the piezoelectric elongation of the unit cell does not occur along the polar directions but along those directions associated with the monoclinic distortion.
Journal ArticleDOI
Tetragonal-to-monoclinic phase transition in a ferroelectric perovskite : The structure of PbZr0.52Ti0.48O3
TL;DR: In this paper, a detailed analysis of the detailed structure of the tetragonal and monoclinic PZT phases on a sample with $x=0.45--0.48$ for which the lattice parameters are, respectively,
Journal ArticleDOI
Stability of the monoclinic phase in the ferroelectric perovskite PbZr1-xTixO3
TL;DR: In this article, the stability region of all three phases has been established from high-resolution synchrotron x-ray powder-diffraction measurements on a series of highly homogeneous samples with $0.42l~xl~0.52.$ at 20 K.
Journal ArticleDOI
Piezoelectric and strain properties of Ba(Ti1−xZrx)O3 ceramics
TL;DR: In this article, the polarization and strain behavior of Ba(Ti1−xZrx)O3 (x=0-03) ceramics are studied and the unipolar strain levels of ∼018% at 40 kV/cm and of ∼025% at ∼120 kv/cm with small hysteresis were obtained for the poramics with 003−xx⩽008.
