To study the coherence of thermodynamic data of the AgNO3-LiNO3-RbNO3 terna
ry system, phase diagram of the binary system AgNO3-LiNO3 has been obtained
between 303 and 550 K by direct and differential thermal analysis techniqu
e. This system is characterized by an eutectic point (25% mol. LiNO3, 445-1
K) and a plateau due to the solid-solid transition in AgNO3 at 434-1 K. In
the solid state the solubility of each component in the other seems to be
nil or negligible (no more than a few percents). Using other thermodynamic
data, the excess properties of the binary liquid (AgNO3- LiNO3) were calcul
ated at 623 K.
