摘　　要：连续氧化铝纤维具有高的强度和模量,是一种重要的高性能无机陶瓷材料。本文主要综述了连续氧化铝纤维制备方法的研究进展及应用,特别是重点介绍了溶胶-凝胶法制备多晶氧化铝纤维。静电纺丝技术的应用也为纳米氧化铝纤维的制备提供了新的思路。采用溶胶-凝胶法时,原材料的选择以及各种影响因素都会影响水解和浓缩的速率,并最终决定氧化铝纤维的性能。最后对氧化铝纤维的发展方向进行了展望。Continuous alumina fiber is an important high performance inorganic ceramic material with high strengthand modulus. Various methods for the continuous alumina fibers preparation and applications are reviewed and awide range of studies about polycrystalline alumina fibers synthesized via sol-gel method are particularly discussed.Electrospinning process has taken a new way for fabricating nano alumina fibers. The starting materials as well as thedifferent factors have an effect on the hydrolysis and condensation rate of the sol-gel process,which in turn determinethe properties of the final materials. At last, the development prospects of alumina fibers are presented.
