Abstract: The degree of the thermal dissocn. of the complex AIF52-  anion of the compd. CaAlF5 formed in the binary system CaF2-AlF3 was detd. by a classical thermodn. method. The approx. value of the enthalpy of fusion of CaAlF5 ca. 96 kJ mol-1, was detd. The degree of the thermal dissocn. of AIF52- anion is 5-10%. This result agrees with the assumption of a high stability of the complex AIF52- anion in this system at 800-900°C.
