Abstract.
A model has been proposed to describe the potential barrier that appears during interaction of two compacted
layers consisting of hydrophilic oxide nanoparticles of different sizes in each layer upon saturation of this
structure with adsorbed water. The dependence of the space charge density of the compacted powder material on
the density of particles in it has been theoretically calculated. The distribution of the potential over the
thickness of contact between two layers consisting of nanoparticles with different sizes has been obtained.
