Thermodynamics of the Evaporation of Scandium Trifluoride and the Composition of Its Vapor

Based on the critical analysis of the experimental and theoretical data on the structure and vibrational frequencies of dimeric scandium trifluoride, the molecular constant values of the Sc2F6 compound are chosen and its thermodynamic functions are calculated. The scandium trifluoride vapor composition is calculated in the temperature range of 1200 to 1825 K. The enthalpies of sublimation and formation of the scandium trifluoride monomer and dimer are determined according to the third law of thermodynamics. The va-lues obtained are added to the IVTANTHERMO software package database.
