Abstract
Thermodynamic equations have been derived that describe the process of the liquid migration from a pore into the bulk of a sintered body. The existence of the migration pressure in a nanocomposite body has been proved and the condition for the equilibrium of a liquid in a pore has been deduced. A concept of a pore critical radius has been formulated and an expression for the radius value has been suggested. All pores, whose radii exceed the critical one, are stable in a sintered body. The pores, whose radii are below the critical radius, are filled by the liquid phase.
