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.
