摘要：

In the present research the tool of impedance spectroscopy was utilized to characterize dielectric behavior of Aurivillius-type ceramics of Bi6Fe2Ti3O18 composition fabricated by hot pressing method from the stoichiometric mixture of oxides Bi2O3, TiO2 and Fe2O3. Impedance spectroscopy was applied to characterize dielectric response of bulk, grain boundary, and material/electrode interfaces of the fabricated polycrystalline ceramic material at both room and elevated temperature. The Kramers-Kronig data validation test was employed in the impedance data analysis. Experimental data were fitted using the CNLS fitting method. Agreement between experimental and simulated data was established.
