Mechanochemical synthesis Ba0.8Sr0.2TiO3

Abstract

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