Calculations of the phase diagram of the AlF/sub 3/-LiF-NaF system up to 35 mol pct AlF/sub 3/ and of the binary subsystems are presented. For the binary LiF-NaF, AlF/sub 3/-NaF, AlF/sub 3/-LiF, and the quasibinary Li/sub 3/AlF/sub 6/-Na/sub 3/AlF/sub 6/ systems, thermodynamic properties of the unary and binary phases are used to numerically generate the corresponding phase diagram. The calculated and measured values are in good agreement. The broad data base thus constructed is used with equations from the conformal ionic solution theory to derive a priori phase equilibria of the AlF/sub 3/-LiF-NaF system. Ternary liquidus temperatures are calculated covering compositions outside the range of measurements. 47 references, 7 figures, 2 tables.
