Structure and relaxor ferroelectric behavior of novel tungsten bronze type ceramic, Sr5BiTi3Nb7O30
Qiuwei He, Siegbert Schmid, Xue Chen +5
A novel lead-free tungsten bronze type ceramic Sr5BiTi3Nb7O30, was prepared by a conventional solid-state reaction route. The room-temperature crystal structure shows an average st…
Dynamic behavior of polar nanoregions in re-entrant relaxor 0.6Bi(Mg1/2Ti1/2)O3-0.4PbTiO3
Kaiyuan Chen, Qi Zhang, Jia Liu +9
The existence of polar nanoregions is the most important characteristic of ferroelectric relaxors, however, the size determination and dynamic of PNRs remains uncertain. We reveal…
Charge effects in donor doped perovskite ferroelectrics
J. Liu, L. Liu, J. Zhang +5
Doping is a widely used method to tune physical properties of ferroelectric perovskites. Since doping can induce charges due to the substitution of certain elements, charge effects…
Phase evolution and thermal stability of high Curie temperature BiScO-PbTiO-Pb(CdNb)O ceramics near MPB
Zhencheng Lan, Kaiyuan Chen, Xiafeng He +8
Piezoelectric and ferroelectric ceramics with a high Curie temperature (Tc) have attracted a growing attention owning to their applications under severe environments. In this work,…
Localized polarons and conductive charge carriers: understanding CaCuTiO over a broad temperature range
Laijun Liu, Shaokai Ren, Jia Liu +6
CaCuTiO (CCTO) has a large dielectric permittivity that is independent of the probing frequency near the room temperature, which complicated due to the existence…
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…
