Ba_(0.6)Sr_(0.4)TiO_3 gel fibers were firstly prepared by the sol-gel method in which acetylacetone was used as the stabilizer of titanate, barium acetate,strontium acetate and butyl titanate were used as starting materials, ethanol absolute-free acetic acid were used as solvent.The green fibers and those sintered at different temperatures were characterized by thermogravimetry analysis(TGA),X-ray diffraction(XRD)and scanning electron microscope(SEM)techniques. Perovskite barium strontium titanate ceramic fibers was crystallized at 1100℃.
