The graphite intercalation compound (GIG) of titanium fluoride has been prepared in a fluorine atmosphere. The GICs prepared from natural graphite and pitch-based carbon fiber were mostly stage-2 compounds with repeat distance 11.28-11.59 A and composition Cll\_15TiF4.1\_6 >. The ESCA spectrum indic
Planar-sheet graphite fluorides, C,F, are prepared at ambient temperature by the reaction of graphite with the transition fluorometallates K2MnF, and KINiF, in anhydrous hydrogen fluoride (AHF). In the case of K?MnF,, this represents the first chemical route to graphite fluorides without use of elem
