The electric conductivity and sedimentation stability of aqueous dispersions of nanodiamond agglomerates are studied. The properties and stability of dispersions were shown to be significantly affected by the pretreatment of particles. The particle size distribution was determined by means of optical microscopy. The sedimentation kinetics of nanodiamond particles in aqueous solutions was studied. The sedimentation kinetic curves showed two sections of fast and slow sedimentation. The obtained results are necessary to develop the technology of nanoporous carriers in analytical and preparative chromatography
