The kinetics of graphitization has been studied using structure • parameters d 002 , Lc and La derived from wide angle x-ray diffraction measurement §• For Glassy Carbon (GC) isochronally (two hours each) heat treated in the temperature range 1000-2800°C, the behavior of these parameters can be studied in three separate regions: (1) For heat treatment temperature (HTT) < 1500°C GC undergoes dehydrogenation, (2) 0 For 1500 < HTT < 2300°C the rna in process is stress re 1 i ef, (3} For HTT > 2300°C graphitization takes place. The activation energy for graphitization in the third region has been determined to be 215 ~ Kcal/mole using the •superposition technique'.
