Spectroscopy study of BaTiO3 obtained from mechanochemically activated oxides mixture

BaTiO3 was prepared by mechanochemical synthesis. A powder mixture of BaO and TiO2 was treated in a planetary ball mill in an air atmosphere for up to 12 h, using zirconium oxide vial and zirconium oxide balls as the milling medium. After 60 minutes BaTiO3 phase was formed. BaTiO3 ceramic was sintered after 120 min on 1300 oC without pre-calcinations step. The heating rate was 10 oC min-1. The formation of phase and crystal structure of BaTiO3 was approved by XRD analysis and Raman spectroscopy. The morphology and microstructure of obtained ceramic powders were examined by SEM method. Sample BaTiO3 obtained from mechanically activated oxides mixture sintered at 1300 oC for 2 h exhibits…
