Furthermore, the crystallite edges, areas of high conduction electron density, are preferential adsorption sites and therefore, if the carbon black through heat treatment coalesces its crystallites, fewer crystallite boundaries are present and less preferential adsorption sites are available which may explain the decrease in nitrogen adsorption.
