A graphite intercalation compound of C,F(MgF& was prepared under a fluorine atmosphere of 1 atm at temperatures of 20-350Β°C. The 1st stage compound has the identity period of 9.3-9.4& ESCA and @F NMR spectra indicate that the chemical interaction of intercalated fluorine with carbon is similar to th

Fluorine-graphite intercalation compounds have been prepared from HOPG and natural graphite powder in the presence of a fluoride such as AgF, WF,, or SbF, at room temperature. The C,F samples obtained were quasi stage 1, 2, and 3 compounds with compositions of Cz ,F-CU hF. The stage 1 hases in the a
