Abstract
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.
