 Perovskite compounds have received keen interest from academic research due to their

unique properties such as ferroelectric, pyroelectric, piezoelectric, and dielectric properties. Nano

sized oxides of strontium doped barium zirconate of general formula Ba1-xSrxZrO3 (x= 0.2, 0.4, 0.6,

0.8) have been prepared by a solid-state procedure. The surface morphology, microstructure, and

phase analysis, of the sintered ceramics were characterized by field emission scanning electron

microscopy (FE-SEM). Scanning electron microscopic studies showed the formation of cubic and

hexagonal nanoparticles with an average grain size of 1.6μm±0.5 and 0.82±0.4μm. Dielectric

studies were carried out as a function of frequency to explore the electrical properties of Sr-doped

BaZrO3.
