Preferred Label : glass-like carbon;
IUPAC definition : An agranular non-graphitizable carbon with a very high isotropy of its structural
and physical properties and with a very low permeability for liquids and gases. The
original surfaces and the fracture surfaces have a pseudo-glassy appearance.;
Scope note : the often used synonyms glassy carbon and vitreous carbon have been introduced as
trademarks and should not be used as terms. from a scientific viewpoint, all synonymous
terms suggest a similiarity with the structure of silicate glasses which does not
exist in glass-like carbon, except for the pseudo-glassy appearance of the surface.
glass-like carbon cannot be described as amorphous carbon because it consists of two-dimensional
structural elements and does not exhibit dangling bonds.;
