摘要
首次采用乙酰丙酮作为钛醇盐的稳定剂，醋酸钡和钛酸丁酯为原料，无水乙醇-冰醋酸作为溶剂，用sol-gel法制备了长达50cm的BaTiO3凝胶纤维。用FT-IR、XRD、TGA．DTA、SEM等手段对凝胶纤维或陶瓷纤维进行一系列表征，最终得到单一钙钛矿相钛酸钡陶瓷纤维，纤维直径4～10μm，具有椭圆形截面。
Barium titanate gel fibers were firstly prepared by the sol-gel method in which acetylacetonewas used as the stabilizer of titanate, barium 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 infrared spectroscopy（IR）,X-ray diffraction（XRD）,thermogravimetry analysis（TGA） and scanning electron microscope（SEM） techniques. Perovskite barium titanate ceramic fibers were of the order of 4 to 10μm in diameter and elliptical shapes in cross section.
