Ba0.8Sr0.2TiO3 was prepared from the starting materials BaCO3, SrCO3 and TiO2 through solid state reaction. Mixtures of these oxides were mechanically activated using a high-energy ball mill at different time intervals from 0 to 120 minutes. X-ray diffraction was employed in order to determine the crystal structure and gave information about composition of phase variation. It was observed that after 40 minutes early synthesis of Ba0.8Sr0.2TiO3 phase occurred. Particle size distribution along with scanning electron microscopy gave very useful information about powder morphology.
