dc.description.abstract | Barium bismuth titanate BaBi4Ti4O15 (BBiT) ceramics have been prepared using non-conventional solid-state reaction route based on mechanochemical synthesis during intensive milling. The X-ray diffraction method was used to determine phase composition. Dielectric properties were investigated in a wide range of temperatures (20-800 degrees C) and frequencies (1.21 kHz-1 MHz). The broad dielectric constant peaks at temperature T-m is frequently dependent. A modified Curie-Weiss relationship is used to study the diffuseness behavior of a ferroelectric phase transition where value of gamma indicates the degree of diffuseness of barium bismuth titanate ceramics. The dielectric relaxation rate follows the Vogel-Fulcher relation with E-a = 0.013 eV, v(0) = 2.09 x 10(8) Hz and T-f = 651 K. All these parameters indicate that BaBi4Ti4O15 is a relaxor ferroelectric. Ohmic conductivities and associated activation energies were evaluated using impedance spectroscopy. | en |
