On thermodynamic characteristics of In-I system compounds

The temperature dependences of the total vapour pressure for solid and liqu id InI2 and liquid InI3 were measured by the static method with a membran-g auge manometer. The heat capacities above phases and solid InI3 were also o btained. The partial pressures In2I6, InI3, InI, In2I4, I-2, I were calcula ted. Absolute entropies and enthalpies of formation InI2 (crII), InI2 (1), In2I4 (g), InI3 (1), InI3 (g), In2I6 (g) were obtained. We used the least s quare method to obtain the mutual consistent sets of data on thermodynamic characteristics of indium iodides in condensed and gaseous phases. The resu lt of this work is the set of standard formation enthalpies and absolute en tropies of the In-I system compounds.
