Surface Areas

The isotherms of bromine on eight carbon blacks and on natural graphite have been related to the known structures of these materials. The surface areas can be calculated from the adsorption isotherms and the size of the graphite crystals can be estimated from the extent of hysteresis on desorption. The isosteric heats of adsorption on the surface and between the layers are each 11 kcal mole−1. The formation of residue compounds displaces the isotherms equally at all pressures.
