摘要：

Ba(Ca1/3Nb2/3)O-3 (BCN) compound was prepared by solid state reaction route. Structural and electrical analyses were done by X-ray diffraction (XRD), Field effect scanning electron microscope (FESEM), temperature and frequency dependent dielectric and impedance study. Final phase compound shows the formation of single phase cubic crystal system. FESEM micrograph shows the development of the grains in various shapes with different sizes. Relative density of sintered compound found to be 97%. Variation of dielectric constant and dielectric loss with temperature show diffuse ferroelectric characteristics. Electrical ac impedance study reveals that behavior of the electrical resistance and poly dispersive nature of the dielectric relaxation.
