Graphitizability

Fig. 2.13 Adsorption of nitrogen on a carbon black before graphitiz-ation. - The difTerential heat of adsorption Ji, plotted against n/n , was determined calorimetrically at 78 K (O, , A) and was also calculated from the isotherms at 78 6 and 90-1 K (+ ). (Courtesy Joyner and Emmett.)...

Singer [22] developed a process for converting 50% of low-cost Ashland 240 isotropic pitch to mesophase by heating the pitch to 400-410°C for approximately 40 hours. During this "heat-soak," mesophase tended to collect at the bottom of the vessel, due to its greater density. The production of highly-oriented, graphitizable...

Simone Pregermain and Jacques Deduit. We think that it is possible, by microdiffraction, to find organized areas in a statistically isotropic coal. We do not know, however, any statistically isotropic cokes which are graphitizable. It may be asked whether the organization as shown in a statistically isotropic coal is pregraphitic.
