Seven sections, in the ternary phase diagram (AgNO3 + LiNO3 + NaNO3) were studied at atmospheric pressure by means of differential thermal analysis (DTA) and differential scanning calorimetry (DSC): X(AgNO3) = 0.1 and 0.8, X(AgNO3)/X(LiNO3) = 3/2 and 2/3, X(LiNO3) = 0.2, and X(NaNO3) = 0.258 and 0.3. The results exhibit two invariant reactions: a eutectoid at T = 380 K and a eutectic at T = 440 K. (c) 2013 Elsevier Ltd. All rights reserved.
