| Abstract: | Several coal tar and petroleum-based binder and impregnating pitches have been aged in an inert atmosphere at 185°C for periods up to four weeks. The effect of the measured changes in the pitch properties with respect to the processing and properties of graphite artifacts is discussed. |
