英文摘要：

Fe3O4 nanoparticles have been widely concerned and researched due to their special physicochemical properties and application in many fields. In this paper, preparation methods of Fe3O4 nanoparticles at home and abroad were introduced. The basic principles and application of ball milling method, precipitation method, hydrolysis method, hydrothermal method, sol-gel method, micro emulsion method and pyrolysis method were mainly discussed. Finally, the development trends of these preparing methods of magnetite nanoparticles were analyzed.
