Abstract

In this paper, BaTiO3 doped with Sb and sintered was investigated. Doped barium titanate nanopowder was prepared by doping pure barium titanate starting from citrate solutions of all components: barium, titanium and antimony. Obtained powders were pressed in to pellets calcined at 800 C for 4 h and sintered at 1300 C for 8 h in air atmosphere. The formation of phase and crystal structure of BaTiO3 was carried out by XRD analysis and Raman spectroscopy. Microstructural 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 Sb doping on barium titanate properties was discussed.
