The deposition of pyrolytic graphite

Abstract : The study of the deposition processes in pyrolytic graphite, made from the gas phase, has been largely empirical. The work presented attempts to show that the deposition is controlled by reactions in the gas phase. Experiments were performed at fast and slow rates of growth using natural, pyrolytic, and commercial graphites as substrates. The deposition processes occurring at various temperatures and pressures for all three substrates are described.
