A comprehensive study of the phase diagram of K0.5Na0.5NbO3-Bi0.5Na0.5TiO3 system
Laijun Liu, Michael Knapp, Helmut Ehrenberg +7
The phase diagram of lead-free piezoelectric (1-x)K0.5Na0.5NbO3-xBi0.5Na0.5TiO3 system has been studied by high-resolution synchrotron powder diffraction, neutron powder diffractio…
Structure and dielectric dispersion in cubic-like 0.5K0.5Na0.5NbO3- 0.5Na0.5Bi0.5TiO3 ceramic
Laijun Liu, Michael Knapp, Ljubomira Ana Schmitt +5
The nature of the cubic-like state in the lead-free piezoelectric ceramics 0.5K0.5Na0.5NbO3-0.5Na0.5Bi0.5TiO3 (KNN-50BNT) has been examined in detail by synchrotron x-ray diffracti…
Structural Contribution to the Ferroelectric Fatigue in Lead Zirconate Titanate (PZT) Ceramics
Manuel Hinterstein, Jerome Rouquette, J. Haines +5
Many ferroelectric devices are based on doped lead zirconate titanate (PZT) ceramics with compositions near the morphotropic phase boundary (MPB), at which the relevant material's…
The nature of iron-oxygen vacancy defect centers in PbTiO3
H. Mestric, R. -A. Eichel, T. Kloss +7
The iron(III) center in ferroelectric PbTiO3 together with an oxygen vacancy forms a charged defect associate, oriented along the crystallographic c-axis. Its microscopic structure…
