| 摘 要： | 采用水热法制备了水基Fe3O4磁流体,利用X衍射仪(XRD)和透射电镜(TEM)对磁粒子的组成、结构及粒径进行了分析,利用古埃磁天平研究了磁流体的饱和磁化强度和稳定性,证实所制得的磁粒子为纯相Fe3O4纳米粒子,平均粒径为9nm左右,磁流体饱和磁化强度为46mT,稳定性较好。

| Abstract: | The water-based Fe3O4 magneto fluid was prepared by hydrothermal method.The sample phase structure and particle sizes were determined by an X-ray diffraction transmission and an electron microscopy,and the saturation magnetization intensity and stability,by a Gouy magnetic balance.The measurement results indicated that the prepared particles are pure Fe3O4 with an average particle size of 9 nm,the saturation magnetization of this magnetic fluid of 46 mT which has good stability. |

| Keywords: | hydrothermal method Fe3O4 magnetofluid saturation magnetization intensity particle size |
