✦ Synopsis

Highly oriented carbon fibers have been intercalated with DMSO-solvated alkali-and substituted ammonium-cations by cathodic reduction. The resulting decrease in resistance was measured and correlated with values of other solvated cation-and anion-intercalation compounds of graphite. The findings indicate similar mobilities of electrons and holes in C,-and C&salts, respectively. Basal spacings of lst-4th stage K+(DMSO),,C; and NMe:(DMSO),C;, which were determined with samples prepared from natural graphite, agree with the model of octahedral solvation of the cations

The rate of fluorine intercalation in graphite is larger in the present system than in other metal fluorides examined previously. X-ray diffraction data indicate that C,F belongs to a hexagonal system with a superlattice of a, = 2a, in the ab plane, accompanying some amount of a bi-intercalation pha

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
