Abstract
Probable mechanisms are discussed of the formation processes of pyrolytic carbon films and soot particles, based on experimental investigations of their formation rates. Both are two-stage processes including nucleation and growth of nuclei. The formation of pyrolytic carbon from methane at temperatures below 1300 K is a molecular process. The activation energy of the formation of a plane nuclei is about 80, and of their growth about 50 kcal/mol. The formation of soot particles may take place in two ways differing in the nature of the nuclei as well as in the structure of the soot particles obtained.Keywords
