Abstract EN
A system consisting of at least two components was considered.
In this system, nanocrystalline material is formed at high temperature, at which diffusion does not limit the mass transport.
The structure results from establishing an equilibrium between surface and volume of the crystallites and their surroundings in isothermal-adiabatic conditions.
The surface of each crystallite is covered with another substance.
On the basis of the performed energy-balance calculations it was concluded that the reduction in the surface area is associated with a decrease in the surface coverage degree and thus with the necessity to provide energy to the system in order to remove chemisorbed atoms.
An increase in the temperature of a nanocrystalline substance to a temperature higher than the preparation temperature results in the formation of a new state of equilibrium.
At temperatures below the maximum temperature only the equilibrium between the gas phase and the surface exists.
