文摘
- •
XRD and XPS data of UxTh1-xO2 films are in agreement with data obtained on bulk.
- •
Oxygen affinity of thorium is much stronger than uranium.
- •
Oxidation of uranium decreases as a function of thorium in the matrix.
- •
XPS made pre and post CV shows thorium enrichment indicating a protective layer.
- •
Higher initial uranium content is directly proportional to higher oxidation states.
