ABSTRACT
The liquidus temperatures of KF–KCl–KI molten ternary system were investigated using thermal analysis of cooling curves method and STA method. The temperature dependences of liquidus temperature vs potassium iodide concentration for [45KF–55KCl mol %]–KI and [66KF–34KCl mol %]–KI melts were determined. Experimental data are summarized as two dependences of liquidus temperature vs. content of KI in KF–KCl. The thermal analysis data were verified by STA. It was confirmed, the KF–KCl–KI system has a eutectic 25KF–31KCl–44KI (mol %) but with a melting point about 750 K.
