Process of fullerene formation and fragmentation is studied in various
zones of fullerene generator. Fullerenes are produced utilizing carbo
n are method, in which graphite electrodes are vaporized in a low pres
sure helium atmosphere by passing an electrical current through the el
ectrodes. The effects of the gas pressure and intensity of the direct
current on fullerene yield are investigated. Maximum fullerene yield o
f 8% is found in a raw soot after the evaporation of graphite by a 60
A direct current, in a helium ambient under the pressure of 8 kPa.
