Abstract:

The irreversible dimensional changes in the a and c directions in pyrolytic graphite were studied as a function of time up to 4 hours and temperature 2500 to 2800 C. The change in the c lattice parameter was also studied. Activation energies for the initial stages of dewrinkling and graphitization have been obtained.
