abstract = "Recently there has been renewed interest in the properties
of the Aurivillius phases as temperature-stable ferropiezoelectrics
[1 ]. Several bismuth-layered crystal structures
and their properties have been investigated in detail [2].
However, a lot of aspects of the preparation and properties of
barium bismuth titanate remain unexplored, whereas being
promising candidate for memory applications.
In present work barium bismuth titanate (BaBi4Ti4Ors-
BBT) was prepared from stoichiometric quantities of barium
titanate and bismuth titanate obtained via mechanochemical
synthesis. Barium titanate (BaTiO3-BT) has been synthesised
from mixture of BaO and TiO2 and bismuth titanate
(Bi4Ti3Or2-BIT) was prepared starling from Bi2O3 and TiO2,
commercially available. \4echanochemical synthesis was
performed in air atmosphere in a planetary ball mill, for BT
during 60 min and for BIT during 360 min. Milling conditions
were: zirconium oxide jars and zirconium oxide balls, ball-to-powder
weight ration 20:7 and determined basic disc and
disc with jars rotation speed. The powder mixture of BT and
BIT was homogenized for 60 min.
BaEli4Ti4ols ceramics were sintered at 1100'C for 2, 4
and 12 hours without pre-calcination step. The heating rate
was 1OoC/min. The formation of phase and crystal structure of
BaTiO3, Bi4Ti3O12 and BaBiaTiaOl5 were approved by XRD
analysis. The morphology of obtained powders and
microstructure were examined by SEM method. The
electrical properties of sintered samples were carried out.",
