Microscopic and dielectric analyses of vanadium and tungsten modified barium zirconium titanate ceramics
(2010-12-01)
Dielectric spectroscopy was used in this study to examine polycrystalline vanadium and tungstendoped BaZr 0.1Ti 0.90O 3 (BZT10:2V and BZT10:2W) ceramics obtained by the mixed oxide method. According to X-ray diffraction ...
Dielectric properties of thermosetting material nanocomposites
(Wiley-Blackwell, 2007-10-05)
The dieletric relaxation properties of thermosetting material nanocomposites based on spherosilicate nanoplatforms were studied from room temperature to 170 degrees C, varying the frequency from 10 to 1000 KHz. Permittivity ...
Dielectric investigations in Sr0.75Ba0.25Nb2O6 relaxor ferroelectric thin films
(Springer, 2009-06-01)
The dielectric properties of Sr0.75Ba0.25Nb2O6 relaxor ferroelectric thin films were carefully analyzed. In contrast to bulk samples which present three distinct dielectric relaxation phenomena Sr0.75Ba0.25Nb2O6 thin films ...
Dielectric and piezoelectric properties of the mechanochemically prepared PZT ceramics
(Kluwer Academic Publ, 2004-08-01)
Mechanochemical synthesis was applied to obtain nanocrystalline powders of composition Pb(Zr0.52Ti0.48)O-3 (PZT). Milling was performed in a planetary ball mill using vials and balls made of zirconia or steel-in order to ...
Properties of BaBi2Ta2O9 thin films prepared by chemical solution deposition technique for dynamic random-access memory applications
(1999-05-01)
We report on the properties of BaBi2Ta2O9 (BBT) thin films for dynamic random-access memory (DRAM) and integrated capacitor applications. Crystalline BBT thin films were successfully fabricated by the chemical solution ...
Piezo and Dielectric Properties of PHB-PZT Composite
(John Wiley & Sons Inc, 2009-09-01)
Flexible piezoelectric composite films made of poly(3-hydroxybutyrate) (PHB) in powder form and lead zirconate titanate (PZT) ceramic powder were obtained by mixing both powders and pressing at 180 degrees C. The effect ...
Size effect on structure and dielectric properties of Nb-doped barium titanate
(Elsevier B.V., 2003-12-20)
It is known that the dielectric properties of BaTiO3 (BT) are strongly dependent on its grain size. Coarse-grained ceramics of pure BT showed lower dielectric constant at room temperature then fine grained. Many authors ...
Investigation of nonlinear dielectric properties in Sr0.75Ba0.25Nb2O6 relaxor ferroelectric thin films
(American Institute of Physics (AIP), 2008-01-01)
The ac and dc driving fields dependence of the dielectric permittivity for the strontium barium niobate relaxor ferroelectric thin films has been investigated. The nonlinear dielectric properties were obtained by using the ...
Synthesis and electrical characterization of tungsten doped Pb(Zr0.53Ti0.47)O-3 ceramics obtained from a hybrid process
(Elsevier B.V., 2007-06-15)
Pure and W-doped PZT ceramics (PZT and PZTW) were prepared by a hybrid process consisting in the association of polymeric precursor and partial oxalate methods. The phase formation was investigated by simultaneous thermal ...
