Abstract
Thermodynamic functions have been derived that describe the processes of nanoparticle consolidation in solid-mobile phase two- and three-phase dispersed systems. An expression for the shrinkage pressure in a two-phase dispersed system has been deduced, which allows one to calculate stresses generating in the bulk of heterophase composite materials in the course of the nanoparticle consolidation. On the strength of these thermodynamic functions criteria have been suggested that allow one to predict the structure of a nanocomposite material.

Summary
The phenomenology, kinetics, and the mechanism of nanoparticle sintering in nanocomposite materials are sufficiently well understood in material science. There are only a limited number of papers reporting the study of the thermodynamic state of nanoparticles [1,2,3,4]. The author has not found publications reporting the studies of the nanoparticle thermodynamic consolidation in dispersed systems. The aim of the present work is to derive thermodynamic functions that describe the nanoparticle consolidation and, based on the resultant relations, to justify some special features of the structure formation of nanocomposite materials. Nanoparticles with a crystalline structure have been the object of the investigation
