本文采用两步微乳液法制备纳米Fe3O4粒子。讨论了水与NP-5（R）的摩尔比、碱浓度、温度、初始总铁浓度和老化时间等因素对纳米粒子形貌和尺寸的影响。结果表明，当R = 6.0，碱浓度为2.5mol/L，反应温度为30 ℃，初始总铁浓度为1.75mol/L时，制备的纳米磁铁矿颗粒尺寸均匀，形貌良好。Ostwald熟化和长时间时效可诱导形成100-400 nm的立方相Fe3O4纳米晶。通过选区电子衍射（SAED）和X射线衍射（XRD）图谱的标定，发现合成的纳米颗粒的晶体结构属于立方晶系。
In this article, a two-step microemulsion method to prepare nano-Fe3O4 particles was adopted. Several factors including molar ratio of water to NP-5 (R), alkali concentration, temperature, initial total iron concentration, and aging time that may affect morphology and size of the nanoparticles were discussed. It was found that such prepared nanomagnetite particles have uniform size and good morphology with R being 6.0, alkali concentration being 2.5 mol/L, temperature at 30°C and initial total iron concentration being controlled at 1.75 mol/L. The Ostwald ripening and long aging time can induce formation of cubic Fe3O4 nanocrystalline with 100–400 nm. The crystal structure of synthesized nanoparticles was found to belong to the cubic system by selected-area electron diffraction (SAED) and indexing the x-ray diffraction (XRD) pattern.
