abstract = "Ferroelectric materials have innumerable properties related totheir spontaneus
polarization, for instance. pyre- and piezoelectricity, which are used for various sensors and
actuators il 1. BaBi4Ti4O12 (BBT) is an r : 4 member of the Bi-layer structured ferroelecrtric
oxide family (Auriviltius phase) [2]. Bi-layered structure ferroelectric material - bismuth
titanate, Bi+Ti:Orz (BIT) and barium-bismuth titanate, BaBi+Ti+Ors (BBT) ceramic powders
were prepared by mechanical synthesis possess. BaBi+TiaOrs was prepared from stoichometric quantities of barium titanate and bismuth titanate obtained via mechanochemical
synthesis. Barium titanate, BaTiOt has been synthesised from mixture of BaO and TiGz and
bismuth titanate, Bi+TirOr: was prepared starting from BiuO: and TiOz, comercialy
available. The reaction mechanism of BBT and the preparation and characteristics of BBT ceramic
powders u,ere studied using X-ray diffraction (XRD) and IR spectroscopy The
phonon modes have been studied by Rarran spectroscopy. The Bi-layered perovskite
structure of BBT cerantic fbrrns at ll00 "C. Microstructure of Bi+Ti:Or1 is in accordiance
with the vierv that Bi,rTilOr:exhibits plate-like grains with thr average grain size increasing
u,,ith the sintering temperature. lt is eviclent that Ba2- aclition leads to the change in the
microstructure development, particularly in the change of the average grain size an;
homogeneity of the grains of BaBi4Ti4O12.",
