Dielectric investigations of vanadium modified barium zirconium titanate ceramics obtained from mixed oxide method
(Elsevier B.V. Sa, 2009-06-24)
Vanadium modified barium zirconium titanate ceramics Ba(Zr(0.10)Ti(0.90))O(3):2V (BZT:2V) were prepared from the mixed oxide method. According to X-ray diffraction analysis, addition of vanadium leads to ceramics free of ...
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 ...
Description of electric field-dependent dielectric permittivity in PMN ceramics
(2019-01-01)
The temperature dependences of the linear and nonlinear components of the dielectric permittivity of PMN ceramics were determined as a function of bias electric fields. The influence of the applied bias electrical field, ...
Non-Linear Dielectric Properties of PLMN-PT Relaxor Ferroelectrics
(Taylor & Francis Ltd, 2008-01-01)
Recent investigations on the non-linear (NL) dielectric properties of relaxor ferroelectrics systems, not only as ceramic bodies, but also, in thin films, have showed a significant technological and scientific interest. ...
Dielectric properties of pure and lanthanum modified bismuth titanate thin films
(Elsevier B.V. Sa, 2008-04-24)
We investigated the dielectric properties of pure and lanthanum modified bismuth titanate thin films obtained by the polymeric precursor method. X-ray diffraction of the film annealed at 300 degrees C for 2h indicates a ...
A close dielectric spectroscopic analysis of diesel/biodiesel blends and potential dielectric approaches for biodiesel content assessment
(ElsevierOxford, 2013-03)
Diesel/biodiesel blends have been more and more used as an alternative fuel due to their economic, social and environmental advantages. This is why, in many cases, legislative policies have been or are being implemented ...
On casimir forces for media whit arbitrary dielectric properties
(Revista Mexicana de Física, 2009)
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 ...
Processing of BiFeO3 thin films to control their dielectric response
(Taylor & Francis Ltd, 2020-05-18)
BiFeO3 (BFO) thin films were studied to control their oxygen-related processing parameters in order to obtain specific electrical characteristics in terms of conductivity and dielectric relaxation. BFO thin films prepared ...
Structural, microstructural and dielectric characterizations of (Bi 0. 5 Na 0. 5)TiO3based lead-free ferroelectric ceramics
(2021-06-01)
(1-x)Bi0.5Na0.5TiO3-xBaTiO3lead-free ceramics have been obtained from the conventional solid-state reaction sintering method. The structural properties were investigated from X-ray diffraction and Raman spectroscopy ...
