PECULIARITIES OF THE ARC DISCHARGE PROCESS IN FULLERENE STRUCTURE SYNTHESIS

摘要

The object of our investigation have been the peculiarities during sublimation of C by arc discharge. The analysis carried out shows that the high temperature obtained on the electrode surface during the arc discharge process allows us to obtain a vapor flux with a large density within the zone of synthesis. The high density increases the probability of creating fullerene type structures and accelerates their growth rate. It is demonstrated that due to this fullerene structures may be produced even at atmospheric pressure and also in an air ambient, while with other methods this can be done only at low pressure and most often in the presence of an inert gas. Attention is paid to the fact that, the multitude of physicochemical processes taking place during arc discharge are prerequisites for the conditions of synthesis to be different at different locations within the discharge space and to give rise to different types of fullerene structures. The temperature balance analysis demonstrates, that different unusual solutions are possible in electrode sublimation and hence to stimulate the growth of certain types of fullrenes.
