Abstract
There is provided a process for producing graphite whiskers by supplying a carbon source compound with a carrier gas into a heating zone in a reactor and decomposing the carbon source compound in a gas phase in the presence of a catalyst, characterized in that the catalyst comprises ultrafine particles of a transition metal which have been obtained by the gas-phase thermal decomposition of a carbonyl compound of a transition metal in the presence of at least one organic compound containing oxygen and/or sulfur.
