本文采用醇-水共热法制备了稳定的Fe_3O_4磁流体并研究了其工艺条件。应用透射电镜、X射线衍射仪、古埃磁天平对Fe_3O_4磁性颗粒的粒径、形貌、磁性等进行了表征,并分析了实验条件对制备的影响。
In this paper, a stable Fe_3O_4 magnetic fluid was prepared by alcohol-water co-heating method and its process conditions were studied. The size, morphology and magnetic properties of Fe 3 O 4 magnetic particles were characterized by transmission electron microscopy, X-ray diffraction and Gurion scales. The effects of experimental conditions on the preparation were also analyzed.
