Abstract
Filamentary growth mechanism of carbon through thermal decomposition of vaporized benzene have been studied.
The film having graphite structure was formed an a base at 1000°C in which the hexagonal layer planes of the graphite are oriented parallel to the base plane. During the thickening of the film, the nucleation of fiber growth occurs. Carbon fibers produced by the decomposition of benzene grow preferably by extending the existing plane of film laterally.
Further it was found that γ-Al2O3 is very effective in producing the carbon fibers. This effect of γ-Al2O3 is due to the works to act as an absorbent and to prevent the formation of soot particles.
