METHOD OF PRODUCING NANOPOWDER OF CARBON-ELEMENT SYSTEMS Russian patent published in 2011 - IPC C01B31/30 B22F9/14 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention can be used in chemical industry. Obtaining nanopowder of carbon-element systems from elements and compounds thereof takes place in thermal plasma of a mixture of hydrocarbons with one component or mixture of components selected from water vapour or carbon dioxide. In the reacting system, total atomic content of carbon C_total, oxygen O_total and element E1_total, which forms a carbon-element system, which satisfies the condition (C_total-O_total)/E1_total> K is maintained, where K is the number of carbon atoms per atom of the element in the gross formula of the obtained nanopowder of carbon-element systems.

EFFECT: invention enables to obtain carbon-element systems without additional process gases for producing plasma and prevents formation of toxic cyanide compounds.
