✦ Synopsis

The experimental techniques for intercalating highly oriented pyrolytic graphite crystals and large size graphite flakes with metal halides are well known and easily carried out. However, as the size of the graphite flakes decrease below 5 microns the conditions for intercalation become more difficult and the results less predictable. Experimental results show that graphite flakes in the 2 micron range can be intercalated with FeCI, under the appropriate conditions of time and chlorine back pressure. The stage formation was confirmed by X-ray diffraction and supported by elemental analysis. A reaction mechanism is proposed and discussed.

The H2 isotherms on graphite, CsFeCIs and ClOFeCI, are identical but when activated, &FeCl, shows higher absorption. This suggests that the metallic Fe produced on activation of CsFeCll in Hz at 375°C is on the surface and is not intercalated. The activated intercalation compound, CsFer&, catalyzes
