The surface fractal dimension, d(fs), is a parameter for the character
ization of the surface roughness which is independent of the size of t
he scale applied on the sample surface. By means of a thermodynamic me
thod d(fs) as well as the limits of fractality can be obtained from th
e nitrogen adsorption isotherm at 77 K in the region of capillary cond
ensation. The applicability of this method is demonstrated on several
disperse materials of different origin.
