Structure study of nanosized La- and Sb-doped BaTiO3

Lanthanum and antimony doped barium titanate powders were prepared by polymeric precursors method through Pechini process. Obtained powder was pressed into pellet and sintering was performed at 1300 °C for 8 h. The formation of phase and crystal structure of BaTiO3 was carried out by XRD analysis, Raman and IR spectroscopy. Microstructure properties such as grain size distribution and morphology of sintered samples were determined using scanning electron microscope. Therefore, it was analyzed relation between grain size, structure and properties of obtained ceramics. Influence of La- and Sb-doping on barium titanate properties was discussed.
