Microwave plasma synthesis of Co and SiC-coated Co nanopowders

This work describes the use of microwave plasma synthesis technique to prepare cobalt nanopowders. The effects of flow rate of plasma gas and carrier gas to the average particle size were studied. Modification of the microwave plasma unit can be used to produce Co nanopowders with SiC coating. The Co and SiC-coated Co nanopowders were characterized by means of transmission electron microscopy (TEM), electron energy loss spectroscopy (EELS) and X-ray diffraction (XRD).
