The phase diagrams of the Cs‐K, Cs‐Rb, Rb‐K, Cs‐Na, Rb‐Na, and K‐Na systems are investigated using the pseudo alloy atom model and the local Heine‐Abarenkov model potential. For the Cs‐K, Cs‐Rb and Rb‐K systems, the curves obtained near the melting point show reasonable agreement with experimental data, and the calculated results predict the presence of a mixture of two phases at low temperatures. Then, the Cs‐Na, Rb‐Na, and K‐Na systems show complete immiscibility.
