Abstract

A new mechanism of fullerene formation is presented. The ”gas-liquid” transition in the expanding flux of carbon atoms is considered as a necessary initial stage. The transition is not terminated at the liquid phase formation as the more powerful processes of network formation predominate. The process of clusters formation starts with the transformation of three-contact structures to stable two-dimensional networks and is governed by the carbon atoms specificity: three-functionality and high rate of chemical reactions. The resulting network is a flat hexagonal lattice with pentagonal ”defects” bending the surface, the free energy minimum structures being fullerenes.
