A model for the structure of `glassy carbon'

Abstract

So-called 'glassy carbon' is characterized by the following physical properties: its hardness is very high; it stands high temperature heat treatments and cannot easily be graphitized by usual heat treatments; it shows, however, a good electrical conductivity although the conductivity is less than that of graphite. Noda & Inagaki (1964) and One may conceive that such oxygen bridges hinder the glassy carbon from graphitization on usual heat treatments at temperatures lower than 1100-1200 C but are destroyed by the heat treatments at temperatures as high as 2500-3000 C.
