β¦ Synopsis
The heats of immersion of graphite degassed at temperatures up to 1000Β°C have been measured in water, methanol and benzene. The removal oloxygen complexes during degassing has been followed quantitatively using a mass-spectrometer system allowing the changes in immersional energetics to be related to the desorbed species.

The extent of chemically detectable acidic surface oxides on graphite has been compared to the total coverage of the surface with oxide. Evolved .gas analysis techniques using a mass spectrometer have been used to determine the composition of the gases evolved (CO, CO,, Hz and H,O) on thermal decomp
The surfaces of Hercules Type A PAN-based graphite fibers both treated (AS) and untreated (ACT) were investigated using thermal deso~tion, krypton adso~tion thermodynamics and ISS t SIMS techniques. Surface treatment enhanced the surface energetics of these fibers on 39% of the surface over the untr
The surfaces of Type HM graphite fibers, both treated (HMS) and untreated (HMU), were investigated using low temperature thermal desorption, krypton thermodynamic analysis, Ion Scattering with Positive Secondary Ion Mass Spectroscopy and Contact Angle Polar/Dispersion Analysis techniques. The surfac
