ABSTRACT:
A method for manufacturing graphite whiskers which comprises: mixing one or more of gasified compounds having a condensed polycyclic structure of two to five benzene rings with a large amount of inert gas containing a small amount of CO, CO.sub.2 or H.sub.2 O; heating said gas mixture at 700.degree. to 1200.degree. C and a substantially atmospheric pressure to generate precursory carbon whiskers comprised of numerous carbon crystals orientated in a form of single sheet which is rolled up like a scroll or a plurality of separate sheets rolled in concentric relationships; and graphitizing said carbon whiskers at temperatures of 2700.degree. to 3000.degree. C in an atmosphere of inert gas.
