A new classification of pyrocarbons is developed, which makes it possible to account for the differences in properties characterizing these materials, based on textural and structural considerations. To obtain this new classification diagram, the classic characterization techniques of texture anisotropy (DEAS, Extinction Angle) are improved and a new way of quantifying it is proposed: the Raman anisotropy factor RA. But, on its own, texture anisotropy proves to be insufficient to differentiate pyrocarbons. Raman spectroscopy, and in particular band enlargement (FWHMD), was then necessary to describe the structural defects of the pyrocarbon network. A 'structure/texture' diagram; (FWHMD=f(OA, Ae or RA)) is constructed and all known pyrocarbo...
