Ba(ZrTi)O3 nanotubes were fabricated by hydrothermal method using Ti-Zr-O nanotube template which obtained via anodization of Ti25Zr substrate and Ba(OH)2 solution.The effect of Ba(OH)2·6H2O con-centrations and hydrothermal temperatures on the microstructure of Ba(ZrTi)O3 nanotubes were investigated. The structural characteristics and surface morphology were examined by X-ray diffraction,X-ray photoelectron spectroscopy,scanning electron microscopy,and transmission electron microscopy,respectively.The results show that BaTi0.75 Zr0.25 O3 nanotubes with the diameter of (70±5)nm and the length of 6μm were prepared suc-cessfully.The optimal process parameters for preparing BaTi0.75 Zr0.25 O3 nanotubes are shown as follows:the concentration of Ba(OH)2·6H2O was 0.08mol/L and the hydrothermal temperature was 150℃.
