HYDROTHERMALLY ASSISTED COMPLEX POLYMERIZATION METHOD FOR BST POWDER SYNTHESIS
Apstrakt
Barium strontium titanium oxy-carbonate (Ba0.8Sr0.2)2Ti2O5·CO3, which is common
intermediate phase in synthesis of barium strontium titanate (BST), has been obtained by
hydrothermal treatment of BST citric precursor solution, previously prepared by
complex polymerization method (CPM). The thermally induced phase evolution from
oxy-carbonate to pure BST was followed using DSC, SEM, X-ray diffraction analysis
and Raman spectroscopy at various temperatures up to 1200°C. The proposed synthesis
route has been proven as a better and faster method for (Ba0.8Sr0.2)2Ti2O5·CO3 powder
preparation as compared to conventional CPM route. The method was found efficient for
production of high purity crystalline BST powders, with small grain size and good
dielectric properties at temperatures T ≥700°C.
