✦ Synopsis
Iron chloride-graphite intercalation compounds synthesized from FeCI, = KC1 molten salts were studies according to the Moessbauer effect. The room temperature Moessbauer spectra of all compounds obtained in the molten salts at 400°C with initial FeCI,IKCl ratio of 90/10:55/45 were found to consist of two intense sets of quadrupole doublets due to two different Fe*+ sites, which had the same isomer shift as anhydrous ferrous chloride but different quadrupole splittings. The total content of Fe2+ in the compounds was more than 87% of all iron ions intercalated, indicating that the compounds obtained were actually ferrous chloride-graphite intercalation compounds. The intercalation process of FeCI, into graphite was also discussed, and the present process was believed to he the direct synthesis of the ferrous chloride-graphite intercalation compounds.
