The alpha-Fe2O3 nanotubes with diameters of 400-700 nm were prepared by calcination of electrospun precursors. The morphology of alpha-Fe2O3 nanotubes is mainly influenced by the water content in solution and heating rate during the calcination process. When the water content is about 17 wt.%, heating rate is 5 degrees C/min and calcination temperature at 500 degrees C for 2 h, the optimized alpha-Fe2O3 nanotubes are obtained. These alpha-Fe2O3 nanotubes have a magnetization (M(s)) of 0.36 emu x (9-1) and coercivity (H(o)) of 1942 Oe and can be used in the nanospace technology.
通过对静电纺丝前驱体进行煅烧制备出直径为400 - 700 nm的α-Fe2O3纳米管。α-Fe2O3纳米管的形貌主要受溶液中的含水量以及煅烧过程中的加热速率影响。当含水量约为17 wt.%、加热速率为5℃/min且在500℃煅烧2 h时，可获得优化的α-Fe2O3纳米管。这些α-Fe2O3纳米管的磁化强度（M(s)）为0.36 emu x (9 - 1)，矫顽力（H(o)）为1942 Oe，可用于纳米空间技术。
