The evaporation and decomposition of cerium tetrafluoride CeF 4 (s) at high temperatures were studied by means of Knudsen Effusion Mass Spectrometry (KEMS). The saturated vapor pressure over CeF 4 (s) was determined by the isothermal evaporation of the sample from Pt Knudsen cell. The enthalpy of CeF 4 (s) sublimation was calculated using the second and the third laws of thermodynamics.
