Способ графитизации углерода шунгитов, включающий получение водной дисперсии наночастиц углерода из шунгита, отличающийся тем, что полученную дисперсию конденсируют и высушивают до получения порошка наночастиц шунгитового углерода, который подвергают обработке в термокамере в атмосфере инертного газа путем быстрого нагрева до 2950°С и более и выдерживают при заданной температуре в течение 5-10 секунд, затем охлаждают до комнатной температуры.Shungite carbon graphitization method, which includes obtaining an aqueous dispersion of carbon nanoparticles from shungite, characterized in that the resulting dispersion is condensed and dried to obtain a powder of shungite carbon nanoparticles, which is processed in a heat chamber in an inert gas atmosphere by rapid heating to 2950°C or more and kept at a given temperature for 5-10 seconds, then cooled to room temperature.
