Everything about Carbon Monofluoride totally explained
Carbon monofluoride (
CF,
CFx, or
(CF)x), also called
polycarbon monofluoride,
polycarbon fluoride,
poly(carbon monofluoride), and
graphite fluoride, is a material formed by high-temperature reaction of
fluorine gas with
graphite,
charcoal, or
pyrolytic carbon powder. Its
CAS number is . In contrary to
graphite intercalation compounds it's a
covalent graphite compound.
Carbon is stable in fluorine atmosphere up to about 400 °C, but between 420-600 °C reaction takes place to give sub
stoichiometric carbon monofluoride, CF
0.68 appearing dark grey. With increasing temperature and fluorine pressure stoichiometries up to CF
1.12 are formed. With increasing fluorine content the colour changes from dark grey to cream white indicating the loss of the aromatic character. The fluorine atoms are located in an alternating fashion above and under the former
graphene plane, which is now buckled due to formation of
covalent carbon-fluorine bonds. Reaction of carbon with fluorine at even higher temperature successively destroys the graphite compound to yield a mixture of gaseous
fluorocarbons such as for example tetrafluorocarbon, CF
4, and tetrafluoroethylene, C
2F
4.
In a similar fashion the recently found
carbon allotrope fullerene, C
60 reacts with fluorine gas to give fullerene fluorides with stoichiometries up to C
60F
48 .
A precursor of carbon monofluoride is the
fluorine-graphite intercalation compound, also called
fluorine-GIC.
Other intercalation fluorides of carbon are:
Application
Carbon monofluoride is used as a high
energy density cathode material in
lithium batteries of the "BR" type. Other uses are a
wear reduction additive for
lubricants, and weather-resistant additive for
paints. Graphite fluoride is also used as both
oxidizing agent and
combustion modifier in
rocket propellants and
pyrolants
