Fractionation of the dispersed nanodiamond powders of detona-tion synthesis is carried out by methods of dynamic sedimenta-tion in centrifuges with surfactant additives. Initial dis-persed nanodiamond powders (with grains’ average size of 12.525 ?m) are subdivided into eight groups by varying of cen-trifuge rotation speed. These groups vary in average size of conglomerates from 28.785 ?m to 3.891 ?m. Adsorption-structural characteristics of each powder of these groups are determined. As ascertained, under condition that average size of conglomerates decreases and pore size is constant, both the specific surface and the porosity of a powder decrease too.
