由０．２ｍｏｌ·Ｌ－１Ｆｅ３＋采用微波诱导加热制备了纳米尺寸的准立方形和纺锤形α－Ｆｅ２Ｏ３粒子，与常规加热方式比较微波加热制得的α－Ｆｅ２Ｏ３粒子粒径小且分布均匀，实验证明无机离子加 Ｈ＋、ＯＨ－和 Ｎａ＋等的加入可明显加速反应速率．
The nanosized quasi-cubic and spindle-shaped α-Fe2O3 particles were prepared by microwave induction heating with 0.2 mol·L-1 Fe3 +. Compared with the conventional heating method, the α-Fe2O3 particles prepared by microwave heating were small in size and distributed uniformly. It is proved that the addition of inorganic ions plus H +, OH- and Na + can obviously accelerate the reaction rate.
