Thin, approximately cylindrical filaments in which
graphene layers are arranged in a scroll-like manner. There is, at least in part, a regular stacking of the layers as in the
graphite lattice, giving rise to
h,k,l, X-ray reflections. The physical properties of
graphite whiskers approach, along the cylinder axis, those of
graphite.
Note:
If there is, due to misalignment of the layers caused by their bending, no three-dimensional stacking order as in
graphite, the term carbon whiskers should be used.
Graphite whiskers and carbon whiskers should be distinguished from more disordered
filamentous carbon.
