✦ Synopsis

The structural evolution of a glassy carbon is studied by analysis of the X-ray diffraction two-dimensional lines. A strong anisotropy is found in the growth of the carbon layers and in their lattice distortions. The results are correlated with the carbonization mechanism of the polymer precursor. H(s) = J(s) -Fcm,o.b) f(s) where I(s) represents the experimental intensity normalized to one carbon atom and corrected from polarisation and absorption, F common is the Compton scattering factor of a covalent carbon corrected for the Breit-Dirac factor and f(s) is the coherent scattering factor for the same atom.
