The conditions for strontium titanate (SrTiO3, ST) nucleation and particle growth were investigated for preparation of ST/ barium titanate (BaTiO3, BT) complex nanoparticles. The conditions with and without ST nucleation were clarified. Epitaxial growth of ST layer on the BT substrate particles was studied using both conditions. Unfortunately, the ST/BT complex nanoparticles with heteroepitaxial interface were not prepared, but a new two-step solvothermal reaction method was developed. Finally, the ST/BT complex nanoparticles without heteroepitaxial interface were successfully prepared.

Nucleation and particle growth conditions of barium titanate (BaTiO3, BT) were investigated for preparation of the BT/strontium titanate (SrTiO3, ST) multilayered nanoparticles. The conditions with and without BT nucleation were clarified. Epitaxial growth of the BT layer on the ST substrate particles was studied using both conditions. The formation of the BT layer on the ST substrate particles was confirmed using the condition with BT nucleation.

Solvothermal Reaction

Barium titanate (BaTiO3) / Strontium titanate (SrTiO3) accumulation ceramics with necking structure of SrTiO3 nanocubes were prepared using a solvothermal method. XRD measurements confirmed SrTiO3 and BaTiO3 with a perovskite structure. The XRD peak intensities of the BaTiO3 increased significantly as the solvothermal reaction was repeated. After heat treatment of the SrTiO3 at 900°C, the particles grew larger and formed necked contacts with each other. As the solvothermal reaction was repeated in order to coat with BaTiO3, the density increased, the porosity decreased, and the thickness of the BaTiO3 layer increased.

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.
