Compositional changes at the interface between thorium-doped uranium dioxide (U_0.97Th_0.03O₂) and Zr before and after annealing at 1700 °C for 18 h were studied by X-ray photoelectron spectroscopy, X-ray diffraction, and Raman spectroscopy. At room temperature, the U_0.97Th_0.03O₂ pellet consisted of hyperstoichiometric UO_2+x with UO₂ and ThO₂, and the Zr sample contained Zr with ZrO₂. After annealing, the former contained stoichiometric UO₂ with ThO₂ and the latter consisted of ZrO₂ along with ZrO₂·2H₂O.

or掺杂二氧化铀与锆之间的界面由于高温退火而发生的成分变化

利用X射线光电子能谱，X射线衍射和拉曼光谱研究了or掺杂二氧化铀（U _0.97 Th _0.03 O ₂）和Zr在1700℃下退火18小时前后的界面组成变化。在室温下，U _0.97 Th _0.03 O ₂颗粒由超化学计量的UO _{2 + x}与UO ₂和ThO _2组成，Zr样品中含有Zr和ZrO ₂。退火后，前者包含化学计量的UO ₂和ThO ₂，后者由ZrO ₂和ZrO组成₂ ·2H ₂ O.
