Thermal analysis has been used to determine the temperaturemdash;composition solidmdash;liquid equilibrium diagrams for the two binary systems, LiBrsngbnd;LiH and LiIsngbnd;LiH. Both are simple eutectic systems with no experimental evidence for the formation of solid solutions. Eutectic compositions of 29.7 mole lithium hydride, mp 453.3deg;C, and 23.5 mole lithium hydride, mp 390.8deg;C, were observed for the bromide and iodide systems, respectively. The values of the chemical potential of each component have been calculated along the equilibrium curves where the solutions are saturated with respect to the pure solids.The limiting slopes of the saturation curves are consistent with the interpretation that lithium bromide and lithium iodide both exist primarily as unhyphen;ionized dimers when dissolved in lithium hydride and that lithium hydride exists primarily as an unhyphen;ionized monomer when dissolved in either lithium halide.
