Preferred Label : pyrolytic carbon;
IUPAC acronym : PVD; CVD;
IUPAC definition : A carbon material deposited from gaseous hydrocarbon compounds on suitable underlying
substrates (carbon materials, metals, ceramics) at temperatures ranging from 1000
to 2500 K (chemical vapour deposition).;
Scope note : a wide range of microstructures, e.g. isotropic, lamellar, substrate-nucleated and
a varied content of remaining hydrogen, can occur in pyrolytic carbons, depending
on the deposition conditions (temperature, type, concentration and flow rate of the
source gas, surface area of the underlying substrate, etc.). pyrocarbon which is synonymous
with pyrolytic carbon was introduced as a trademark and should not be used as a term.
the term pyrolytic carbon does not describe the large range of carbon materials obtained
by thermal degradation (thermolysis, pyrolysis) of organic compounds when they are
not formed by chemical vapour deposition (cvd). also, carbon materials, obtained by
physical vapour deposition (pvd) are not covered by the term pyrolytic carbon.;
