Abstract

This work proposes a new method for mass production of carbon allotropes synthesis by arc-plasma. In particular, carbon vapor is produced from graphite electrode by introducing a buffer gas into the electrode gap to generate an intense gas outflow and fast evacuation of the produced vapor from the hot plasma zone. Study of the influence of the gas flow dynamics differently supplied to the hot plasma zone during the fullerenes synthesis was studied and the relationships between different gas flow rates, applied power, diameters of used electrodes and fullerenes productivity and yield were established. The new proposed method allows a significant increase of fullerenes productivity. Copyright © 2004 by Marcel Dekker, Inc.
