摘要：

Six fractions of ultradispersed diamonds with different aggregate sizes are separated from a hydrogel stable with respect to sedimentation by the step-by-step ultracentrifugation. Distribution of carbon phases and impurities between the fractions is studied, and the fraction densities are calculated and experimentally determined. The structure and surface chemical composition of the dispersed phase in the diamond hydrogel are shown to be nonuniform.
