A New Method to Produce Superfine and Nano-Sized Fe Powders: Spark Plasma Discharge Process
Superfine and nano-sized Fe powders were prepared by a spark plasma discharge process in deionized water. The powders were characterized by Field Emission Scanning Electron Microscope (FESEM) with Oxford Inca EDX, and X-ray diffraction (XRD). The experimental results indicate that the powders prepared by the process have a bimodal size distribution, high purity, single phase, good spherical shape and high yield.
