微波辐射制备均匀α-Fe2O3纳米胶粒的研究
Study on the Preparation of Monodispersed Nanoparticles Hematite by Microwave Irradiation
【摘要】 对用微波加热的方法制备均分散 α-Fe2 O3纳米胶粒进行了研究 ,讨论了影响粒子大小和形状的主要因素 ,结果表明 :微波辐射能使反应时间大大缩短 ,并且通过改变不同的溶液组成可以制得纺锤形和立方形的 α-Fe2 O3纳米胶粒。
【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.
