Preparation and Electrical Resistivity of Intercalation Compounds of Graphitized Cokes with Antimony Halides

Preparation of intercalation compounds of a graphitized electrode coke and a synthetic graphite with SbCl₅, SbCl₄F, SbCl₂F₃ and SbF₆ have been described and stages have been characterized by X-ray diffraction technique. On applying pressure a de-intercalation of antimon pentahalides have been found. The stability of intercalation compounds of graphitized cokes to pressure, temperature, organic solvents and aqueous HCI is lower than that of natural graphite compounds. Electrical resistivity of compacted intercalation compounds of different stages parallel and perpendicular to pressure direction decreases with increasing pressure, intercalant concentration and particle size. Intercalation increases anisotropy of electrical conductivity in graphitized coke and decreases it in synthetic graphite.
