ADHESION IN TWO-PHASE MELTS OF ALKALI METAL HALOGENIDES

Adhesive interaction of phases in two-phase LiF+KBr, LiF+CsCl, LiF+RbBr, LiF+KI, LiF+CsBr, LiF+RbI, and LiF+CsI melts is analyzed. The adhesion of phases is found to grow as the temperature increases as a result of the superposition of thermal motion of ions and changes in the compositions of coexisting phases. The adhesion of phases is shown to be the less the wider the concentration interval of immiscibility of components. At the same temperature, the adhesion of the phases increases with the decreasing difference in the size of the mixed ions.
