摘 要：Nano-sized barium strontium titanate (BaxSr1-x TiO3, BST) powders were synthesized with hydrothermal and solvothermal methods at 120 ℃ for 4 h based on the reaction precursor of barium acetate, strontium acetate, tetrabutyl titanium and (CH3 )4NOH. The crystalline phase, particle size and morphology of the BST powders were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Influences of reaction temperature and reaction time on the morphologies of powders were also discussed.
