The high-temperature Knudsen effusion method was used to study the vaporization processes and thermodynamic properties of dysprosium trifluoride in the temperature range 1280-1440 K. Data on the partial vapour pressure of DyF3 as a function of temperature and the enthalpy of sublimation of DyF3 were obtained. Using the value of the enthalpy of formation of solid DyF3, available in the literature, the enthalpy of formation of the gaseous molecule of dysprosium trifluoride and its atomization energy were calculated. At 1382 K, the partial vapour pressure of Dy2F6 over dysprosium trifluoride was obtained and the Gibbs energy of the gaseous reaction (Dy2F6)=(2DyF3) was evaluated.
