The barium strontium titanate(BST) precursors were prepared by SolGel method by using strontium acetate, barium acetate and tetrabutyl titanate(Ti(OC4H4)4) as the raw materials. Ten percent of TiO2(anatase),TiO2(rutile) and onedimensional TiO2 were added respectively into the precursors. The three different products were produced from the precursors of different additives by the hydrothermal method with the same hydrothermal condition. The phase structure and morphology of products were characterized by Fourier transform infrared spectrometer(FTIR),Xray powder diffraction (XRD) and scanning electron microscope (SEM).The growth mechanism and formation reason of the hydrothermal products were discussed. The results indicated that the precursors with TiO2(anatase) could produce the columnar crystal of BST.Adding the onedimensional TiO2 prepared by hydrothermal method in the precursors can prepare BST crystal with onedimensional morphology.
