β¦ Synopsis
The nuclear hyperfine technique of time-differential perturbed angular correlations has been applied to the study of graphite intercalation compounds. Values are obtained for the electric field gradients and the quadrupole frequencies of the intercalated probe nuclei. Specifically, three species are distinguishable in C,InCl,. Other systems are now being studied. 112. Structural properties of intercalated graphite fibers 108. In-situ Raman scattering studies of intercalation kinetics C.

stage 1 potassium-graphite intercalation compound was recently reported. This compound differs from those already known by its structure, which includes two metal layers in the same gallery. It has roughly KC, stoichiometry. This compound was studied under high quasi-hydrostatic pressures up to 25 k
## By means of alternating current calorimetry and X-ray diffraction, a study has been made of the phase transition behavior of graphite-ICl intercalation compounds slowly heated from 290 to 340 K. The heat capacity vs. temperature plots exhibit A-type anomalies at 305 f I, 312 5 1 and 315 + 1 K.
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
