摘　　要：以硝酸铝、酒石酸为原料,添加的纺丝助剂为聚乙烯吡咯烷酮(PVP),用溶胶-凝胶法制备了氧化铝纤维。在纤维制备时,添加氧化硼,研究了氧化硼对纤维形貌的影响。结果表明,添加氧化硼的凝胶纤维在1200℃烧结后,物相主要为α-Al2O3,纤维的直径为22μm,纤维表面变粗糙。Alumina fibers were prepared by sol-gel method using aluminium nitrate,zirconium oxychloride, tartaric acid as raw materials, polyvinylpyrrolidone （PVP） as spinning additive. The effect of boric oxide on alumina fibers morphology was studied. The result indicated the fibers were obtained by firing at 1200℃, with α-Al2O3 phase, rough surface and 22μm in diameter.
