abstract = {Structural and dielectric properties of
SrBi2(Nb1-xTx)(2)O-9 solid solution, (SBNT), with x = 0.0,
0.1, 0.2, 0.3, 0.5, 0.7, 1.0 were investigated. Crystal
structure at room temperature was analyzed by X-ray
diffraction study. SBNT exhibits an Aurivillius structure
and the c lattice constant decreases with increasing
concentration of Ta in the solution. The studies of real
(epsilon') and imaginary (epsilon '') parts of permittivity
as a function of temperature (20-500 degrees C) and
frequency (0.1-100 kHz) were carried out, as well. The
anomalies of epsilon'(T) and epsilon ''(T) associated with
phase transition from the tetragonal paraelectric phase (PT)
to the orthorhombic ferroelectric phase (F-O) were observed.
They are strongly dependent on the Ta content in the
solution. The grain structure and chemical composition were
examined by a scanning electron microscope (SEM), with an
energy dispersion spectrometer (EDS). The EDS analysis
indicated a homogeneous distribution of all elements of
ceramics within the grains. (C) 2009 Elsevier Ltd and Techna
