The DTA method was used to obtain the phase diagram of the Na+, K+/CN-, I- ternary reciprocal system. This system forms completely miscible solid solutions with two ternary minima with the parameters xNa+ = 0.50, xI- = 0.57, θ = 412°C, and xNa+ = 0.75, xI- = 0.20, θ = 428°C. The NaI-KCN diagonal is the stable diagonal.
