Scanning electron microscopy and
EDX studies on magnetic nanoparticles is a good characterization tool before
proceeding to magnetic fluid preparation. Scanning electron microscopy gives
idea about the grain size. X-ray diffraction data and scanning electron
microscopy data, if combined together, gives exact nature of grain structure
and size distribution of the material. EDX studies can be used to confirm the
elemental composition. Starting precursors for zinc ferrite magnetic fluid are
zinc oxide, iron oxide, oleic acid and kerosene.
