Abstract: It is proved that the bond of diamond nanoparticles during their connection – agglomeration, is formed mainly due to a weak – about 0.05 eV – bond of unpaired electrons from the subsurface layers of each particle. This property distinguishes diamond nanoparticles from all known types of nanoparticles.

Keywords: diamond nanoparticles, weak covalent bond, agglomeration, suspension.
