| Popis: | The published data concerned with the determination of the composition ranges of uranium oxides, UO 2+ x , U 4 O 9− y and U 3 O 8− z , which have been determined using thermogravimetric, X-ray diffraction and electrochemical techniques are critically assessed. U 4 O 9 and U 3 O 8 have quite small domains of composition and the assessment of such data has carefully considered the uncertainties in the experimental determinations. In addition, the thermodynamic properties of U 4 O 9 and U 3 O 8 , enthalpies of formation and transformation, entropies, and thermal capacities are analyzed and selected to build a primary data base for compounds. |
