Morphology-controlled synthesis of barium titanate nanostructures.
This study reports the synthesis of morphology-controlled BaTiO(3) nanostructures such as spherical, cube-shaped and rod-shaped BaTiO(3) using a molten-salt synthesis method. This method synthesized products from a reaction of BaO/BaCO(3) and TiO(2) with a eutectic mixture of NaCl-KCl flux at 700 degrees C for 1 h. The experiment used powder X-ray diffraction, field emission scanning electron m...
متن کاملSynthesis of Barium-zinc-titanate Ceramics
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered at 1250 °C for 2h with a heating rate of 10 °C/min. X-ray diffraction analysis of obtained powders and sintered samples was performed in order to investigate changes of the pha...

متن کاملDielectric properties of binary polyvinylidene fluoride/barium titanate nanocomposites and their nanographite doped hybrids
Binary polyvinylidene fluoride/barium titanate(PVDF/BaTiO3) and its nanographite (GN) doped ternarynanocomposites were fabricated using a simple solution casting process followed by compression molding. The dielectricbehavior of such hybrids over a wide frequency range was studied. Additions of GN with contents close to the percolationthreshold were found to be very effective to...
متن کاملH all effect and dielectric properties of Mn - doped barium titanate
BaMn Ti O (0# x # 0.01) ceramics have been prepared using a sol–gel method. The Hall coefficient, x 12x 3 leakage conductance and dielectric constant were measured. The Hall effect confirms that the charge carriers of the ceramics are electrons, and the electronic concentration n 5 1/ ueRu decreases with increasing Mn 31 41 concentration. We propose that Mn and Mn substitution of Ti can partial...
