Synthesis of Ni and bimetallic FeNi nanopowders by microwave plasma method

Nickel nanopowders can be synthesized by microwave plasma synthesis method. The effect of the feeding rate of the precursor material to the average particle size and crystallinity was studied. FeNi bimetallic alloy nanopowders were also successfully synthesized by pre-mixing the respective precursor raw materials before feeding into the plasma reaction zone. The Ni and FeNi nanopowders were characterized by means of transmission electron microscopy (TEM) and X-ray diffraction (XRD).
