摘　　要：首次采用乙酰丙酮为钛醇盐的稳定剂,醋酸钡、醋酸锶和钛酸丁酯为原料,无水乙醇-冰醋酸作为溶剂,利用Sol-Gel法于1100℃得到单一钙钛矿相钛酸锶钡陶瓷纤维。用TG、XRD、SEM等手段对产物进行表征。Ba0.6Sr0.4TiO3 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℃.
