摘 要：<正>The AlN whiskers were composed by the Al2O3-C system with some CaF2 and NH4Cl addition under the condition of the carbothermal reduction treatment of 1450 C and 2h as well as nitrogenous atmosphere. The composed AlN whiskers were analysed and the results show that some whiskers morphology such as plate cwoed, brached corrugated were observed and the ratios of length to diameter change greatly. The composed whiskers are not even. some surface quality is not high. TEM analyse show that the fiber axes are normal to[0112] and [1101]. The mechanism of the growth of the whiskers is supposed to be VLS（Vapor-Liquid-Solid）
