摘要
通过化学共沉淀法制备水基纳米磁流体,利用激光散射粒度仪、扫描电镜、X射线衍射仪、振动磁强计等手段表征磁流体,结果显示制得的磁流体主要成分为Fe3O4,颗粒成球形,粒径为50纳米左右,PDI=0.13,且粒度分布较窄,具有顺磁性,饱和磁化强度为36.37emu/g。
Nano-magnetite particles （ferrofluid, Fe304） were prepared by chemical co- deposition method.SEM, VSM, XRD, Malvem laser Particle Size Analyzer were employed to characterize the properties of prepared ferrofluid.The conclusion could be made that the obtained iron oxide particles with sphere morphology mainly were magnetite （Fe3O4） ; its size was ca.50 nm and size distribution was narrow, PDI = 0.13; the ferrofluid was paramagnetic and its saturation magnetization was 36.37emu/g.
