摘　　要：利用机械力化学原理,通过行星式高能球磨机,在水溶液中球磨金属铁粉,成功制备了Fe3O4纳米粉末。通过X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）等技术手段对生成相进行了表征,Fe3O4纳米粉末粒径为30-80 nm。体系中铁的氧化物的相对含量随球磨时间的延长而逐渐增加,随球料比、球磨转速的增大而增加。Based on the theory of mechanochemistry, the iron powder was ball-milled in high-energy planetary ball mill, Fe3O4 nanoparticles were prepared successfully. The as-formed phases were studied respectively by XRD, SEM, TEM. The nanoparticles of Fe3O4 with the diameter of 30 - 80 nm. In the system, the relative content of Fe3O4 increased with the milling time, the ratio of grinding media and material and the speed of rotation.
