In this study, structural, dielectric and ferroelectric properties of BaZr 0.025 Ti 0.975 O 3 ferroelectric ceramics have been investigated. The compound was synthesized using solid state reaction technique. It is observed that the synthesized compound have perovskite crystal structure. As the sintering temperature increases from 1200°C to 1250°C and 1300°C, the average grain size increases from 0.62μm to 2.82μm and 3.20μm respectively. Moreover, the domains with “water-mark” and “lamellar” features are observed in SEM micrographs. The dielectric measurements as a function of temperature show a decrease in Curie temperature on increasing the sintering temperature. The decrease in Curie temperature is attributed to the decreased tolerance factor of the perovskite ABO 3 structure. There is enormous increase in the permittivity with the increase in grain size. The coercive field decreases and the remanent polarization increases as the grain size increases.
