DOI:https://doi.org/10.2172/4784636· OSTI ID:4784636

Equations for the vapor pressure of uranium pentafluoride were derived. The melting point of uranium pentafluoride was determined both by experiment and by simultaneous solution of the solidus and liquidus vapor pressure equations. Physical properties of uranium pentafluoride determined besides vapor pressure were: melting point == 348 deg C (experimental); 353 deg C {+13, -- 16) (simultaneous solution); heat of vaporization (solid) = 36.6 plus or minus 3.0 kcal/mole; heat of vaporization (liquid) = 24.7 plus or minus 3.8 kcal/mole; and heat of fusion = 11.9 plus or minus 4.2 kcal/mole.
