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 کاملAn XPS Investigation of Hydrothermal and Commercial Barium Titanate Powders
Hydrothermal and commercial barium titanate powders were examined for undesirable impurity phases. Compositional differences in the powder were evaluated using x-ray diffraction ( XRD ), x-ray fluorescence ( XRF ), and x-ray photoelectron spectroscopy (XPS). A brium-rich impurity phase, virtually undetectable by XRD, was detected via XPS. Barium impurity phase peaks were detected at binding ene...
متن کاملSynthesis of single-crystalline perovskite nanorods composed of barium titanate and strontium titanate.
We report the solution-based synthesis of single-crystalline nanorods composed of barium titanate (BaTiO3) and strontium titanate (SrTiO3), which yields well-isolated nanorods with diameters ranging from 5 to 60 nm and lengths reaching up to >10 mum. Electron microscopy and diffraction measurements show that these nanorods are composed of single-crystalline cubic perovskite BaTiO3 and SrTiO3 wi...
متن کاملSynthesis and characterization of Barium Strontium Titanate (BST) micro/nanostructures prepared by improved methods
Nowadays various methods are presented for synthesis of barium strontium titanate (BST) nanopowders with different morphology and properties. Each of these (BST)s has got individual characterization that makes it suitable for a special application. Every method has a special quality, causes it to have preference over the other methods. Low processing temperature is a desired point which most of...
