Abstract The ferroelectric barium strontium titanate (Ba1-xSrxTiO3) is a homogeneous solid solution prepared from the mixture of barium titanate (BaTiO3), strontium titanate (SrTiO3) and titanium (IV) isopropoxide. Barium strontium titanate (BST) nanomaterials with improved permittivity and dielectric properties due to their nano-properties have attracted great interest for extensive and versatile applications as super capacitors, dielectrics, ceramics and catalysts. Introduction of metal ion dopants into the parent system of BST significantly alters its structural, morphological, electrical, optical and dielectric characteristics. This review is aimed at addressing synthesis, characterization methods, photocatalytic and electrical applications of metal ions doped BST nanomaterials. The effect of doping BST, through metal ions, on its properties and application with most probable reasons have been thoroughly discussed.

Doping effect of Sb on Pb-free barium strontium titanate was investigated. The Sb doped (Ba,Sr)TiO3 ceramics were prepared by solid reactions in 1473-1623 K by employing 0~1.2 wt% Sb2O5 as main additives. Density changes with sintering temperature were determined. The morphology and microstructure of the Sb doping samples were analyzed by SEM. The dielectric properties such as permittivity and dielectric loss were measured. It was found that addition of Sb benefited to low temperature high density sintering process. When the addition amount of Sb2O5 was about 0.6 wt%, the dielectric loss of (Ba,Sr)TiO3 was decreased from 1.9% to about 0.4% while the dielectric constant was kept over 2000. Possible mechanism of the improvement by Sb addition was discussed too.
