Bottom Line: With this model, we find the sediment volumes, the emergent, and the bound dispersion medium.We formulate a new approach for determining the equivalent radii of the particles from the sediment and the emergent (different from the Stokes method).We also describe an easy manner to apply algebraic method for determining the average volumetric mass densities of the ultimate sediment and emergent, as well as the free dispersion medium (without using any pycnometers or densitometers).

ABSTRACT
We introduce a close packing model of the particles from the disperse phase of a liquid dispersion. With this model, we find the sediment volumes, the emergent, and the bound dispersion medium. We formulate a new approach for determining the equivalent radii of the particles from the sediment and the emergent (different from the Stokes method). We also describe an easy manner to apply algebraic method for determining the average volumetric mass densities of the ultimate sediment and emergent, as well as the free dispersion medium (without using any pycnometers or densitometers). The masses of the different components and the density of the dispersion phase in the investigated liquid dispersion are also determined by means of the established densities. We introduce for the first time a dimensionless scale for numeric characterization and therefore an index for predicting the sedimentation stability of liquid dispersions in case of straight and/or reverse sedimentation. We also find the quantity of the pure substance (without pouring out or drying) in the dispersion phase of the liquid dispersions.

Mentions: In order to determine the densities, respectively, ρs of the ultimate sediment and ρ of the dispersion medium, we use two identical cylindrical containers, K1 and K2, with radius of the internal basis R = 0,013 m (Figure 3).
