A graphite susceptor for use in a tube furnace during the production of a continuous length of a carbonaceous fibrous material. The graphite susceptor has a passageway extending therethrough which includes an entrance portion and an exit portion with the cross-sectional area of the entrance portion being of a smaller cross-sectional area than that of the exit portion. In a preferred embodiment of the invention the cross-sectional area of the entrance portion has a rectangular configuration, and is adapted for use in the production of graphitic tapes consisting of a plurality of continuous graphite filaments.
