Abstract
High-pressure-induced structural phase transitions in alkali halide crystals have been studied. The pressure of the B1-B2 phase transition in crystals of finite dimensions is studied with the use of pair-interaction potentials within the theory of inhomogeneous electron gas. It is shown that the pressure of polymorphous transformation depends on the initial crystal dimensions. The anomalous dependence of the transition pressure on the dimensions of crystalline grains in lithium fluoride is considered and interpreted. Some structural and surface characteristics of the B1 and B2 modifications of a number of alkali halide crystals are calculated in the approximation of seven coordination spheres.
