✦ Synopsis

In the system FeCl,/Cl,/graphite, threshold values exist both for the vapor pressure of the halide and for the chlorine pressure. If the pressures are lower than required by the law of mass action,

(pressures in mbar),

the intercalation is blocked. The equilibrium is attributed to the nucleation process. For the nucleus, the composition C,FeCI, , results. The inhibition of the reaction can also be overcome by the addition of traces of FeCI,. In that case, a different mechanism is assumed for the nucleation, in which the adsorption of the gaseous complex Fe,C& is the initial step.

The amount of expansion on exfoliation is determined principally by the parent stage rather than the actual intercalate concentration. The amount of expansion increases with increasing stage of the parent compound before desorption. For the same parent stage, a higher concentration produces a larger
