✦ Synopsis

The action of liquid chlorine on graphite has been studied by gravimetric, dilatometric and radiocrystallographic means. Around -20°C and according to the nature of the graphite, the compounds C&I and C&I corresponding to stages 3 and 4 respectively, were obtained. The interplanar distance is practically double that of pure graphite or 6.70 A. The intercalation involves a decrease in electrical resistivity in the direction parallel to the layers comparable to that observed for bromine. It was not possible to prepare compounds richer in chlorine by cooling to -40 and -78°C.

The intercalation of lanthanides is possible by two different ways: direct action of the metal vapor in metallic tubes sealed under vacuum or by heating compressed mixture of powders of the metal and of graphite. The first method was used only for the most volatile metals: samarium, europium, thuli
