Objects of the research - physicotechnical processes of phase and structurally-phase transformations of carbon in the course of graphite and electrodischarge electroexplosion in the organic fluids, also gained carbon nanomaterials. Research methods - mathematical modelling; electrophysical experiment in vitro; research of CNM by methods of an element X-ray spectral microanalysis, an X-ray diffraction analysis, electronic microscopy combined with microdiffraction, mass spectrometry, infrared and Raman spectroscopy. The bases are developed for a purposeful high-energy synthesis of different carbon nanostructures in the processes of electroexplosion of graphite conductors and electrodischarge treatment of organic fluids. For the first time the methods of mathematical modelling resulted in gaininig the conditions for a high-energy synthesis of fullerenes and nanodiamonds in the course of electroexplosion of cylindrical graphite conductors which are determined by relations between the inserted energy and sublimation energy, and also between the radius of a conductor and the capacity and inductance of an electric circle. Use of the gained conditions of synthesis and tempering has allowed to synthesize and explore purposefully the CNM. Presence in the electroexplosion products of fullerenes, carbon nanotubes and nanodiamonds is confirmed. The method of gaining CNM as a result of the continuous electrodischarge treatment of liquid hydrocarbons is offered. It is shown that electrodischarge treatment of liquid hydrocarbons at specific inserted energies from 0.5 to 2.5 MJ/l is accompanied by formation of amorphous carbon of a nanocrystalline structure, hydrogen and low gaseous hydrocarbons. Dependences of CNM yield from the inserted energy are gained. Yield of CNM as a result of electrodischarge treatment of organic fluids does not exceed 10 %.
