Ferroelectric properties of Sm doped BaTiO₃ bulk ceramics Available to Purchase

In the present work, the structural and optical properties of Ba_1-xSm_xTiO₃(x=0.0& 0.05) bulk ceramics have been reported. The barium titanate (BaTiO₃) has tetragonal perovskite structure with geometry ABO₃. Solid state reaction method was used to synthesize the bulk ceramics. These synthesized bulk ceramics were characterized by x-ray diffraction (XRD), ferroelectric and UV-vis spectroscopy. The XRD results understandably showed thesingle-phase crystalline nature of all the samples and declined the presence of any secondary phase. The band gap of BaTiO₃ and Sm doped BaTiO₃ was found to be 2.42 eV and 3.02 eV. It increases with increasing the doping concentration. P-E hysteresis loops have estimatedthe value of remnant polarization =0.3849µC/cm² and coercive field=-1.5718 kV/cm for BaTiO₃ and remnant polarization =0.4783µC/cm² and coercive field=-1.4193 kV/cm for Sm doped BTO.
