Lipson, T. Puryaeva, V. Savenko] BET adsorption, electron-microscopy, and X-ray diffraction analysis have been employed to study the vibrodispergating kinetics of crystalline lithium fluoride particles under conditions of simultaneous irradiation of the material with a flux of thermalized neutrons with low intensity I = 100 neutron/(cm2 s). It has been found that, during vibratory treatment of the powder, the stationary state of the material microstructure is reached much earlier than the limiting (equilibrium) value of its external (specific) surface area is established. The reaction rate constants have been determined for the polygonization and recrystallization, which take place in the material during its vibratory grinding. The influence of the neutron irradiation on the numerical values of these constants has been revealed. The energy parameters of the processes occurring in the system have been analyzed taking into account the heat release caused by neutron absorption in the material.
