【摘要】采用化学共沉淀法制备Fe3O4纳米粒子,选择NH3.H2O作为沉淀剂,并与Fe2+和Fe3+的混合溶液同时同速滴加到由氨水和硝酸氨组成的缓冲溶液中,制得了磁性Fe3O4纳米粒子.考察了磁性纳米粒子合成的一些影响因素,并用透射电镜(TEM)、X射线粉末衍射(XRD)、红外光谱等方法对其性质进行了初步表征.更多还原

【Abstract】 In this work,nanometer magnetite(Fe3O4) particles were prepared by the chemical co-precipitation method,NH3·H2O was chosen as the precipitating agent,and was added dropwise together with the mixed aqueous solution containing ferric and ferrous ions to the buffer solution composed of NH3·H2O and ammonium nitrate to produce nanometer Fe3O4 particles.Some influence factors on the size and characteristic of the product were investigated,and preliminary characterization was also performed by means of TEM,XRD and IR spectrum.更多还原
