Study Phase Triangles LiNO3 – NaNO3 – NaI, LiNO3 – KNO3 – KI and LiNO3 – RbNO3 – RbI Ternary Mutual Range Systems Li,M || I,NO3 (M – Na, K, Rb)

By differential scanning calorimetry (DSC) was first investigated experimentally determined complexes and phase characteristics of equilibrium points of the invariant three-phase triangles reciprocal systems of several Li,M || I,NO3 (M – Na, K, Rb). The compositions of eutectic (mol%) Li,Na || I,NO3 : (E1 ) NaNO3 – 42,5%, NaI – 5,0%, LiNO3 – 52,5% with a melting point of 178 °C. Li,K || I,NO3 (E2 ) LiNO3 – 44,0%, KI – 2,0%, KNO3 – 54,0% (mol) with a melting point of 117°.
