dc.description.abstract | BaBi4Ti4O15, an Aurivillius compound,was synthesized by a cost-effective soft chemical route.The precursor was prepared by precipitating Bi-and Ba-oxalatesinsideaTiO2 powder suspension.A phase pure orthorhombic BaBi4Ti4O15 was synthesized by heating the precursor powder at1000 1C. The phase formation behavior was investigated using TG-DSC and XRD.Densification behavior of the powder and microstructure development in sintered pellet was examined.Temperature dependent dielectric study of the ceramic has been investigated in the temperature range300–780K and frequency range of 1kHz–1MHz.The broad dielectric constant peaks at temperature Tm was frequency dependent.The dielectric relaxation rate follows the Vogel–Fulcher relation with activation energy ¼ 0.2639 eV,relaxation frequency ¼ 4.951021 Hz, and freezing temperature ¼ 620 K. All these parameters indicate that BaBi4Ti4O15 is a relaxor ferroelectric. | en |
