This paper discusses the method of arc discharge in gaseous phase (ADG) and it has been used for production of iron, nickel and their mechanical mixtures based on Me-C composites. The product has been synthesized using are plasma -chemical installation with vertical location of the reactor which has the mobile cathode. The mechanical mixture of graphite and metals powders has been added into the anode along its axis. Investigations of micro- and nanostructures of produced composites have been carried out using the transmission electron microscope (TEM). The Me-C nanocomposites (Me = Fe, Ni, Fe + Ni) with the structure simillar to the nucleus – cover structure have been produced. It has been noticed their response to the magnetic field action. Me-C nanocomposite material has been taken out of soot by magnetic separation of parietal soot suspension in hydrocarbons. The initial fullerite crystals, which are contained in soot before extraction process, have been shown. The self-descriptiveness and the high speed performance of qualitative and quantitative analysis of the method for soluble nanomaterials have been pointed out.
