Using Calvet’s micro calorimeter, we have determined the enthalpies of formation for two quasibinary fused salt mixtures ››LiNO3 – KBr‹‹ and ››KNO3 – LiBr‹‹ at 450 °C . At this temperature the nitrates used are in the molten state, while the bromides are solid.
Two different types of measurements were performed in order to obtain data on the quasibinary enthalpies of mixing; (a) in dilute solutions, (b) in concentrated solutions.
Our experimental results gave us the following analytical expressions.
