讨论了多晶石墨和热解石墨的内表面能对三种现象的可能影响：（a）碳的热力学“标准”状态，（b）石墨化过程，以及（c）高温下石墨的结构稳定性。为此，我们从多个来源计算了基面和边缘面的表面焓和自由能，并讨论了它们在高达 3000K 的温度下的依赖性。已经提出了更直接测量基底表面和“边缘”表面能的方法的建议。
A discussion is presented describing the possible influence of the internal surface energy of polycrystalline and pyrolytic graphites on three phenomena: (a) the thermodynamic “standard” state of carbon, (b) the graphitization process, and (c) the structural stability of graphites at high temperatures. In order to do this, the surface enthalpies and free energies of the basal surface and edge faces have been calculated from a number of sources, and their temperature dependence up to 3000K discussed. Suggestions have been made for methods to measure both basal surface and “edge” surface energies more directly.
