Роль карбида кремния в электродуговом синтезе высших фуллеренов

The influence of silicon atoms in the graphite electric arc zone on the formation efficiency of higher fullerenes C76, C78, C80, C82, C84, C86, etc. was studied. Additives of silicon carbide from 0 to 6.3 wt. % of composite graphite electrodes and optimization of the conditions of their evaporation make it possible to obtain soot with a content of higher fullerenes up to 15.5 wt.% in the extract and at the same time with a high total yield of fullerenes 10.5 wt.%.
