摘要
The intercalation of magnesium chloride into graphite has been studied as a function of the temperature, in the presence of a chlorine gas. The second stage compound has been obtained at 580 °C, the average formula of which is C9MgCl2. By cointercalation of MgCl2 and CoCl2, at 600 °C, MgCl2/CoCl2 ratio equal to 4.5 and during ten days, the first stage compound C5.65(MgCl2)0.97(CoCl2)0.03 has been obtained. It only contains traces of CoCl2. A theoretical mechanism of this cointercalation is proposed.
