【Abstract】 Preparation of uniform α Fe 2O 3 nanoparticles by microwave irradiation was studied. The influence of parameters on the size and shape of particles was analyzed. Results show the reaction time was shortened, and different shapes α Fe 2O 3 nanoparticles, for example ellipsoidal shape, tetragonal shape, were prepared by forced hydrolysis of ferric salts under different conditions.更多还原
