In this study , the metal-chloride graphite intercalation compounds were synthesized using gas phase reaction . Synthetic graphite powder which possess different geometric morphology and microstructures, were used as carbon host materials in order to study the host effect on the synthesis and structure of graphite intercalation compounds. The structure and morphology were studied using X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The distribution of intercalant inside the host materials was also analyzed quantitatively using electron probe microanalyser. Only stage 1 structure was found for iron chloride graphite intercalation compounds.
