Abstract: Using the thermal analysis method the phase diagram of the KBF4-KF-KCl system was determined. The system is a simple eutectic one with the coordinates of the eutectic point of 61.4 mole % KBF4, 19.4 mole % KF, 19.2 mole % KCl and the temperature of the eutectic crystallization of 422°C. The dependence of the excess Gibbs energy of mixing on the composition was calculated using the theory of regular solutions. From the analysis of this property it follows that a significant ternary interaction of all present anions takes place, most probably due to the exchange substitution of fluorine atoms in the complex fluoroborate anion by chlorine ones.
