How grain boundaries modify the high-temperature dielectric response of ferroelectric electroceramics like BaTiO(3)?
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Dielectric properties of BaTiO(3) ferroelectric ceramics were studied over wide frequency and temperature ranges. The materials showed complex dielectric behaviors, which included an anomalous increase of permittivity ...
Exploring the electromechanical response and electric field-induced dielectric anomalies in PMN-PT electroceramics
(2021-06-01)
Electromechanical and dielectric properties of PMN-PT ferroelectric ceramics are investigated. In particular, dielectric response studies focus on the investigation of the influence of the DC applied electric field on the ...
Impedance spectroscopy and dielectric properties of flash versus conventionally sintered yttria-doped zirconia electroceramics viewed at the microstructural level
(Wiley-BlackwellMalden, 2013-12)
The defect chemistry-modulated dielectric properties of dense yttria-doped zirconia ceramics prepared by conventional sintering (at 1350°C-1500°C) and electric field-assisted flash sintering (55 V/cm at 900°C) were studied ...
La3+ - induced (micro)structural changes and origin of the relaxor-like phase transition in ferroelectric lead barium niobate electroceramics
(SpringerNew York, 2014-07)
Lead barium niobate (Pb1-xBaxNb2O6, PBN) ferroelectric materials have been and are the subject of numerous studies in literature due to their potential for wide-ranging applications in the electronic industry. In this work, ...

(Royal Society of Chemistry, 2021-04)
Crystal structure and properties of Sr11Mo4O23treated at 1100 and 1400 °C were studiedviasynchrotron X-ray powder diffraction and thermogravimetric analysis, coupled with mass spectrometry. Synchrotron studies reveal the ...
New dielectric anomalies in the A-site highly deficient NaxNbO3 electroceramics
(Elsevier, 2020)
Highly sodium deficient Na0.6NbO3 (NN) ceramics were prepared and characterized. Their mean structure could be described by a mixture of the predominant P polymorph (S.G. Pbma) and the Q phase (S.G. P2(1)ma), at room ...
