以FeCl3·6H2O和FeSO4·7H2O水溶液为原料，以NH4OH为沉淀剂，N2H4·H2O为抗氧化剂，在连续微波照射下水热合成纳米fe3o4。x射线粉末衍射（XRD）、红外光谱（FT-IR）和扫描电镜（SEM）测试结果表明，合成的Fe3O4磁铁矿纳米颗粒的平均直径为10nm。用振动样品磁强计（VSM）测量了fe3o4纳米颗粒的磁性能，表明纳米颗粒在室温下具有较高的饱和磁化强度。利用纳米fe3o4制备了基于水的磁流体（MFs），并分别用Gouy磁天平、毛细管流变仪和旋转流变仪对其性能进行了表征。
Fe3O4nanoparticles were hydrothermally synthesized under continuous microwave irradiation from FeCl3·6H2O and FeSO4·7H2O aqueous solutions, using NH4OH as precipitating reagent and N2H4·H2O as oxidation-resistant reagent. The results of X-ray powder diffraction (XRD), FT–IR spectroscopy and scanning electron microscopy (SEM) measurements showed that the synthesized magnetite (Fe3O4) nanoparticles had an average diameter of 10nm. The magnetic properties of the Fe3O4nanoparticles were measured using a vibrating sample magnetometer (VSM), indicating that the nanoparticles possessed high saturation magnetization at room temperature. The Fe3O4nanoparticles were used to prepare magnetic fluids (MFs) based on water, and the properties of the MFs were characterized by a Gouy magnetic balance, a capillary rheometer and a rotating rheometer, respectively.
