Abstract
The density of a randomly formed coagulative structure is shown to depend on the number of primary particles in the aggregates. The influence of the particle roughness, the thickness of equilibrium interlayers of disperse medium between the particles, and the anisometry of the particles on the density, of the coagulative structure the inhomogeneity of the mass in disperse systems has been assessed.
