AB  - Barium strontium titanate powder Ba0.8Sr0.2TiO3 (BST) has been obtained by
hydrothermal treatment of precursor solution containing titanium citrate, previously
prepared by complex polymerization method, and barium and strontium acetates.
The powders were calcined at 700 °C, pressed into pellets and further sintered at
1280 °C for a various sintering times (from 1 to 32 h), and structural parameters,
phase composition, dielectric and ferroelectric properties were investigated. Rietveld
refinement analysis of BST ceramics showed that predominant phase was tetragonal
BST with monoclinic Ba6Ti17O40 (B6T17) as a secondary phase. Phase contents
determined by Rietveld refinement match well with the results of energy dispersive
X-ray analysis and ICP analysis. SEM micrographs of sintered samples revealed the
abnormal grain growth where elongated twinned grains of BST grow in a matrix of
smaller B6T17 grains. Dielectric and ferroelectric properties of BST ceramics have
been correlated with density of sintered compacts, phase composition, structural
parameters and microstructure. The sample sintered for 16 h showed the highest
density (93% ρt), as well as the highest value of dielectric constant (~2300) and
remanent polarization – Pr (2 μC/cm2) among investigated samples.
