Ferroelectric samples Sr1?xBaxTiO3 (BST), where x = 0, 0.2, 0.4, 0.6, 0.8 and 1, were prepared using the tartrate precursor method annealed at 1200 °C for 2 h. X-ray diffraction, “XRD”, pattern analysis verified structure phase. The crystallite size of SrTiO3 phase was calculated to be 83.6 nm, TiO2 it 72.25 nm. TEM images showed that crystallites agglomerated, due their nanosize nature. AC res...

BaTiO3-CoFe2O4 composite films were prepared on (100) SrTiO3 substrates by using a radio-frequency magnetron co-sputtering method at 750 °C. These films contained highly (001)-oriented crystalline phases of perovskite BaTiO3 and spinel CoFe2O4, which can form a self-assembled nanostructure with BaTiO3 well-dispersed into CoFe2O4 under optimized sputtering conditions. A prominent dielectric perc...

Helical antennas have been a popular antenna configuration for various applications for its simple structure. This work describes the study on a novel, custom-shaped dielectric loaded helical antenna incorporated on an advanced material, which is Barium Strontium Titanate (BST). This material, which presents the researcher with an advantage in size reduction due to its high relative permittivit...

Atomic Layer Deposition of Platinum on Strontium Titanate Surfaces Tremendous energy savings and environmental benefits are possible from improved catalysts for chemical manufacturing and emissions reduction. Breakthroughs in catalyst development will be enabled by precise methods for synthesizing nanostructured materials. Atomic layer deposition (ALD) is a thin film growth technique that is cu...

Abstract In this study, we prepared a homogeneous fine powder of barium titanate (BaTiO 3 , BT) doped with different concentrations strontium (x = 0, 0.05, 0.125, 0.15, 0.20, and 0.3) having the composition Ba 1-x Sr x TiO (barium titanate, BSr T). XRD patterns Rietveld refinement revealed existence single tetragonal phase structure for BSrxT, 0–20%, cubic BSr30%T. The physical properties pure ...
