METHOD OF OBTAINING CARBON NANO-TUBES Russian patent published in 2009 - IPC B82B3/00 C23C16/26 

FIELD: chemistry.

SUBSTANCE: invention relates to microstructural technologies, namely to nanotechnology, in particular, to method of obtaining fibrous carbon nanomaterials which consist from carbon nano-tubes, by method of precipitation from gas phase. Reactor is filled with inert gas and its central part is heated. Then reaction mixture containing carbon source and ferrocene catalyst source is injected, which under impact of temperature turns into vapour. Vapour is kept in hot zone by ascending inert gas flow, source of padding for precipitation of catalyst nanoparticles and growth of carbon nano-tubes being introduced into reaction mixture. As padding source used are complexes of macrocyclic polyesters with salts of metals selected from line Ca, Ba, Sr, Y, Ce, which have temperature of decomposition lower than catalyst source, and serve as continuous source of padding.

EFFECT: synthesis of carbon nano-tubes is performed continuously, which results in increase of carbon nano-tubes output.
