Abstract
The liquidus temperatures of the ternary mutual KF–KCl–KI system with KF/KCl molar ratios of 0.8 and 2 are determined by thermal analysis of cooling curves and differential scanning calorimetry. The dependences of the liquidus temperature on the potassium iodide content for the [45KF–55KCl, mol %]–KI and [66KF–34KCl, mol %]–KI melts are determined. The results are generalized in the form of two sections of the ternary mutual KF–KCl–KI system. The data obtained by thermal analysis agree with the data obtained by differential scanning calorimetry and thermogravimetry. Synchronous thermal analysis confirms that the KF–KCl–KI system is characterized by the 25KF–34KCl–41KI (mol %) eutectic with a melting temperature of 750 K.
