Three artificial graphites have been studied by X-ray, electron microscope, and adsorption techniques. Surface areas were calculated from the adsorption isotherms and from the X-ray spectra. The two sets of areas were of the same order of magnitude and varied from 18 m.2/g. for the graphite of smallest surface area to 385 m.2/g. for the graphite of largest surface area. The appearance of the graphites under the electron microscope was in qualitative agreement with the adsorption and X-ray data.
