CHARACTERIZATION OF BARIUM BISMUTH TITANATE OBTAINED BY MECHANOCHEMICAL SYNTHESIS
Апстракт
Barium bismuth titanate, BaBi4Ti4O15 (BBT) was prepared by homogenization and
sintering of mixture of stoichiometric quantities of BaTiO3 and Bi4Ti3O12 obtained via
mechanochemical synthesis. The reaction mechanism of BaBi4Ti4O15 formation and the
characteristics of BBT powders and ceramics were studied using XRD, Raman
spectroscopy and SEM. The results confirmed that BaBi4Ti4O15 was formed by
tetragonal symmetry. Only 4 Raman modes are clearly observed. Ba2+ ions randomly
occupy the Bi sites of a pseudo-perovskite layer and may enter in a bismuth oxide layer.
BaBi4Ti4O15 ceramics possess the plate-like structure typical for layered structure
materials.
