Abstract

The kinetics of impregnation of graphite surface by water-salt solutions has been described theoretically. This process for the indicated group of carbon materials was shown to be of diffusive character. The equation to estimate the time of graphite materials impregnation by water-salt solutions has been derived. This parameter was shown to be determined by the state of surface, geometry structure of pores, type of salt, and its solution concentration as well as by the parameters of air diffusion through salt solution. The process of salt crystallization on the surface of graphite materials has been analyzed theoretically. The equilibrium value of wetting angle (i.e., the state of graphite surface) was revealed to be the main parameter determining this process. The dependence between part of crystalline salt phase on the surface of graphite material and wetting angle has been derived. The chemical activation of graphite material surface results in the reducing of wetting angle and, respectively, to the increasing of the part of crystalline salt phase was shown.
