Electrically conductive carbon flakes and films are prepared in high yield by the pyrolysis of cyclic aromatic hydrocarbons, optionally halogenated, in the presence of a dehydrogenating agent at about at least 800 DEG C. Flakes of thicknesses up to 20 mu m and lengths up to 1 cm on a side are metal-like in appearance and have a conductivity of about 200-300 S/cm at room temperature. By heat treatment to 2600 DEG C, graphitic order is improved and the conductivity rises to APPROX 10000-15000 S/cm. |
