Abstract
The influence of potassium carbonate additions from 1 to 12 wt % and the helium pressure on the content of higher fullerenes C76, C78, C80, C82, C84, C86, etc., in soot is studied. The optimum conditions of the evaporation of composite graphite electrodes are found: they provide the formation of soot with a high content of higher fullerenes (up to 11.4 wt %) in an extract.
