CASCARINI DE TORRE, L.E. et al. Characterization of shungite by physical adsorption of gases. An. Asoc. Quím. Argent. [online]. 2004, vol.92, n.4-6, pp.51-58. ISSN 0365-0375.

Shungite is a natural carbonaceous mineral,abundant in Russia. Their properties are currently under study and their applications are continuously growing. In this work the surface properties for a sample of shungite were characterized using physical adsorption of N2, Ar, O2 and CO2. Pore size distribution and pore volume were calculated. Real and apparent densities were determined andthe adsorption energy distribution was calculated for N2, Ar and CO2. The sample of shungite shows a mesoporous surface with a narrow size pore distribution. Theirspecific surface is relatively low and the surface seems to be rather homogeneous.
