摘　　要：用高温分解法,以乙酰丙酮铁为前驱体,二苯醚为溶剂,制备了四氧化三铁(Fe3O4)纳米粒子,并对其形貌和磁性能进行表征。结果表明,制备的Fe3O4纳米粒子多呈立方体状,粒径分布较为均匀(~15 nm),易聚集,但其在环己烷中具有较好的分散性;其饱和磁化强度为41.35 emu/g,矫顽力和剩余磁化强度分别为28.47 Oe和2.06 emu/g。Fe3O4 nanoparticles were synthesized by the thermal decomposition method using iron acetylacetonate as precursor and diphenyl ether as solvent.The results show that most of as-prepared Fe3O4 nanoparticles have cubic shape and uniform particle size distribution(~15 nm).These Fe3O4 nanoparticles are easy to agglomerate,but they have good dispersion in cyclohexane.The saturation magnetization,coercivity and remanent magnetization of as-prepared Fe3O4 nanoparticles are 41.35 emu/g,28.47 Oe and 2.06 emu/g,respectively.
