Abstract

Ceramic materials are widely used as base material for composite film and high frequency resistor because of their better insulating behavior. So, a good and careful study of dielectric and conductivity parameters are required for ceramic material. Polycrystalline ceramic (Bi0.9La0.1)(Fe0.5Ti0.5)O3 (referred as BLaFTO-10 in this communication) was successfully synthesized by traditional solid state reaction method. Structural analysis done with XRD characterization, which confirms the single-phase formation of the compound at room temperature. Scanning electron microscopy is used to examine the morphological study which confirms the polycrystalline nature of the sample. EDX study confirms the formation of compound and presence of all element in the as prepared sample. In this paper focus is made on the study of dielectric measurement, conductivity and impedance analysis in a wide range of frequency (1 kHz to 1 MHz) and temperature (250C – 5000C). Ac conductivity follows the universal Jonscher’s power law. Dielectric spectrum reveals the high values of dielectric permittivity and low value of tangent loss. These interesting features could be utilized for electronic applications.
