Résumé :

A review of the thermochemical data for the vaporization of the oxides and carbides of uranium was made to derive indirect values for the heat of sublimation of uranium from the corresponding thermodynamic cycles. The values obtained are in good agreement with the direct value determined mass-spectrometrically by the authors, ΔH0298,8(U) = 125,5 ± 2.5 kcal/g.atom and with the value ΔH0298,8(U) = 126 ± 5 kcal/g.atom also determined mass spectrometrically by De Maria, Burns, Drowart and Inghram (J. Chem. Phys. 32 [1960] 1373). © 1964.
