Dielectric tunability in (1-x)[Pb(Mg 1/3Nb 2/3)O 3]-xPbTiO 3 ceramics for tunable devices application
The dielectric properties of the 0.65[Pb(Mg 1/3Nb 2/3)O 3]-0.35PbTiO 3 ferroelectric ceramic composition were investigated viewing the capability to be used for tunable microwave applications. The dielectric response has ...
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
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 ...
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 ...
Ferroelectric switching and dielectric response of P(VDF-TrFE)/PMMA blends
The ferroelectric and the dielectric behaviors of binary blends formed by an equi-molar Poly(vinylidene fluoride trifluoroethylene) copolymer [P(VDF-TrFE)] and Poly(methyl methacrylate) [PMMA] were investigated, for several ...
Dielectric and ferroelectric characteristics of barium zirconate titanate ceramics prepared from mixed oxide method
(Elsevier B.V. Sa, 2008-08-25)
Barium zirconium titanate (BZT) ceramics were prepared by mixed oxide method. X-ray diffraction showed the presence of a single phase while Raman scattering confirmed structural transitions as a function of different Zr/Ti ...
