摘要
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．
Nanometer-sized quasicubic and spindle a-Fe2O3 particles were prepared by microwave heating from 0.2mol·L-1Fe3+ salts solution. The obtained α-Fe2O3 particles have smaller sizes and uniform distribution by contrast with conventional heating. Inorganic ions such as H+, OH-and Na+, can obviously affect the precipitating rate of spindle α-Fe2O3 and accelerate the hydrolysis of ferric ions.
