Abstract
DISINTEGRATION of vitreous carbon exposed to potassium vapour is thought to result1 from the enhancement—by the formation of intercalation compounds—of stresses already present in the structure. Fischbach2 describes a model of vitreous carbon in which small crystallites of disordered graphite material are bonded by non-trigonal cross-links. It might be expected that such a structure would be reflected in a higher heat of combustion of the material.
