Description Iron-based nanoparticles in powder form were synthesised by plasmochemical method. Surface-wave discharge was sustained in low-pressure argon atmosphere by 2.45 GHz microwaves. Properties of the discharge were analysed by optical emission spectroscopy and digital photography. The nanopowder captured on filters was investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The powder consisted of nanoparticles containing mainly ferrite alpha-Fe and magnetite Fe3O4. Size of synthesised nanoparticles was between 9 and 14 nm.
