EN The structure of most porous materials is quite complex. In the last two decades the characterisation of the structure of these materials made a milestone progress owing to the use of fractal geometry. At present it is generally accepted that the fractal models of pore structure describe the real structure better than the classical models which assume the existence of macro-, meso- and micropores of simple geometry. Pores are essential in materials applied as catalysts, filters, membranes, adsorbents. Thus the knowledge of the specific surface area, pore size and roughness of pore-solid interface is the prime importance. These parameters in the length scale 5-1000 angstrom can be estimated by the small-angle X-ray scattering (SAXS) method. The SAXS studies were performed on different porous silica materials, zirconia aerogels and metal foils electrodeposited in galvanostatic conditions. The fractal concept was applied to facilitate the interpretation of SAXS results.
