Special Thermodynamic Features in the Li-LiD System at Phase Equilibrium

摘要

The Li-LiD system is considered under conditions of liquid-vapor phase equilibrium. The liquid is a binary infinitely dilute solution of lithium deuteride in lithium, and the coexisting vapor phase is a multicomponent chemically reacting ideal mixture of gas components. The previously unknown existence of azeotropy in the Li-LiD system is revealed with the concentration of components expressed in atomic fractions of deuterium and lithium in both phases, and the temperature and concentration limits of the azeotropic zone are found. Note is made of the practical importance of the thus obtained regularities.
