Abstract:
Using the thermodynamic properties of scandium trifluoride, calculated on the basis of new experimental data on heat capacity, the enthalpy of sublimation of scandium trifluoride $\rm ScF_3$(cr) was found. The combination of this quantity with the accepted value of the enthalpy of $\rm ScF_3$(cr) formation leads to a refined value of the enthalpy of $\rm ScF_3$(g) formation.
