In this present study the (Pb 1/2 Ba 1/2 )(Ni 1/2 W 1/2 )O 3 , [PBNW] perovskite compound has been formulated and synthesized by adopting a solid-state reaction technique. The detailed structural, morphological, and electrical characterization has been carried out to explore its characteristics for further application in the field of electronic devices and sensors. With the help of x-ray diff raction analysis orthorhombic structure has been recognized. Dielectric, impedance spectroscopy, and a.c. conductivity analysis has been carried out through a wide range of temperatures as well as frequency (temperature range 25–500 °C, frequency range 1 kHz to 1 MHz). Presence of a single semi-circular arc from Nyquist analysis points toward the grain contribution of the sample. An equivalent circuit model has been developed to explore its electrical behavior. The activation energy, as well as the charge carrier mobility, has been estimated. Methodical studies for dielectric properties at high temperatures are accomplished for analysing electrical inhomogeneity allied with surfaces, grain boundaries, or grains, which are imperative for fundamental characterization and device fabrication.
