Abstract
IT is well known that potassium atoms lodge themselves between the basal planes of the graphite lattice to produce intercalation compounds in many different forms of graphite1. Glassy carbon is a very defective, randomly oriented polycrystalline form for which the 0002, 10&1bar;0 and 11&2bar;0 lines are very diffuse but clearly present. Intercalation compounds in such a material would seem to be improbable and, indeed, glassy carbon is inert to most molten metals.
