F. Faucanillac et al., MASS-SPECTROMETRIC STUDY OF THE GAS-PHASE DURING CHEMICAL-VAPOR-DEPOSITION OF PYROLYTIC CARBON, Journal de physique. IV, 5(C5), 1995, pp. 89-96
The pyrolysis of CH4, of C3H8 and of the mixture 20C3H8/80CH(4) was in
vestigated in a hot wail CVD reactor by mass spectrometry. Experiments
were conducted as a function of temperature and of surface-to-volume
(SN) ratio of the substrate. The main by-products of the pyrolysis wer
e identified and reaction mechanisms were proposed taking into account
homogenous decomposition/formation reactions. Cyclic species are poss
ibly involved in the formation mechanism of pyrocarbon.
