The ordering in carbon formed as a result of annealing of pine wood shavings in argon at T = 1900 and 2250A degrees C has been studied by high-resolution transmission electron microscopy. It is established that the ordering involves graphene layers, which serve as the basis for the formation of monolithic structural elements in the form of ribbons. Graphene layers are bent to various degrees and their spacing in ribbons varies within 0.34-0.38 nm. The coarsening of ribbonlike structural elements takes place via the formation of new graphene layers from the matrix component.
