Many quasi-binary phase diagrams which comprised of KAlF4 with other fluorides or complex fluorides have made by visual-polythermal. DTA and XRD methods. Results indicated that the more composition of second components is similar to that of KAlF4, the more influence on liquid and eutectic of the system would be observed. Stable and simple fluorides are difficultly soluble in molten KAlF4 below 800℃. From mentioned, it is deduced that the structure of molten KAlF4 appears to be comprised of moleoular KAlF4 as well as ions K^+ and AlF4^-. Molecular KAlF4 is relatively stable and is the main part in the melt.
