Abstract
Graphite was irradiated by CO2 laser of energy 10 J and pulse width 4 mu s. SEM and XRD examinations were carried out before and after laser irradiation. It was observed that XRD pattern changed after irradiati on and new entities were seen on surface. Amorphous graphite was also irradiated and it was found that it became partly crystalline. The cha nges were explained on the basis of phase changes induced by high pres sures and temperatures during laser irradiation.
