✦ Synopsis

A study of conversion of rhombohedral sequences into hexagonal graphite structure was carried out in order to clarify the role of defects in the transformation G Rh + G"ex. We have shown that, the fraction of rhombohedral graphite transformed at a given temperature of anneal into hexagonal graphite depends on the residence time. It seems that under continuous grinding some rhombohedral structures are transformed into biperiodic, some of which in annealing revert to hexagonal via rhombohedral. The results give nood information about the existence of rhombohedral sequences which are " involve; in the graphitization process.
