All varieties of substances consisting of the element carbon in the allotropic form of graphite
irrespective of the presence of structural defects.
The use of the term graphitic carbon is justified if three-dimensional hexagonal crystalline long-range order can be detected in the material by diffraction
methods, independent of the volume fraction
and the homogeneity of distribution of such crystalline domains. Otherwise, the term non-graphitic carbon
should be used.
