Abstract
It is established by x-ray structure analysis that the oxide film form ed on the surface of uranium during oxidation by dry oxygen at pressur es of 0.1-0.001 Pa and temperatures of 500-700 degrees C for several h ours consists of UO2 with U4O9 inclusions. Near the surface of the ura nium the temperature of the alpha-->beta phase transition is lowered b y 150-160 degrees C in comparison with the transition in the bulk of t he metal, and the low-temperature stabilization of the beta phase of u ranium is observed.
