Method for manufacturing graphite whiskers using condensed polycyclic hydrocarbons

摘要

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, CO2 or H2O; heating said gas mixture at 700 DEG to 1200 DEG 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 DEG to 3000 DEG C in an atmosphere of inert gas.
