Abstract
The surface contribution to the thermodynamic potential for bulk and nanodimensional particles of ion crystals is estimated with the help of the electron statistical theory of ion crystal lattice. A number of size effects associated with the excess surface energy of ultradisperse particles are considered. In particular, the possibility of stability loss in the crystal lattice upon the transition of the surface energy to the range of negative values under a high pressure is predicted.
