Abstract

The porous structure of MgB2 has been investigated using atomic force microscopy (AFM) and sorption techniques. The fractal dimension and surface roughness parameters were evaluated from (AFM) and nitrogen adsorption–desorption isotherms measured at −196 °C for MgB2 sample. Adsorption capacity, specific surface area, and fractal dimensions were determined from adsorption–desorption isotherms. The sorption isotherms of MgB2 samples were S-shaped and belong to type II according to the IUPAC classification. The results of fractal dimensions of MgB2 surface determined on the basis sorptometry and AFM data are compared.
