Carbon monofluoride (CF, CFx, or (CF)n), also called polycarbon monofluoride (PMF), polycarbon fluoride, poly(carbon monofluoride), and graphite fluoride, is a material formed by high-temperature reaction of
Carbon is stable in a fluorine atmosphere up to about 400 °C, but between 420-600 °C a reaction takes place to give sub
In a similar fashion the recently found carbon
A precursor of carbon monofluoride is the fluorine-graphite intercalation compound, also called fluorine-GIC.
Other intercalation fluorides of carbon are:
- poly(dicarbon fluoride) ((C2F)n);
- tetracarbon monofluoride (TCMF, C4F).
Graphite fluoride is a precursor for preparation of
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.[5]
Carbon monofluoride is commercially available as Carbofluor-brand materials.[6]
