title: Preparation of barium strontium titanate Ba(1-x)Sr(x)TiO(3) (0<or= x <or=0.2) single-crystal nanorods by a novel combined method.
abstract: An ultrasonic irradiation method was applied to the sol/gel synthesis of the single-crystal cubic barium strontium titanate Ba(1-x)Sr(x)TiO(3) (0<or= x <or=0.2). The characteristics of the composites were examined by X-ray diffraction, thermogravimetric analysis, differential thermal analysis, transmission electron microscopy and high-resolution transmission microscopy. The diameters and lengths of typical resultant Ba(0.8)Sr(0.2)TiO(3) are in the range of 70-100 nm and 650-1000 nm, respectively. In addition, the stoichiometric sonogel formation and its heat-treatment process, the relationship between x of Ba(1-x)Sr(x)TiO (3) and the crystal structure, the relationship between synthesis condition of sonogel and morphology have been discussed.
