Defect equilibria, electrical conductivity and oxygen diffusion

Kato, Masato ; Nakamura, Hiroki ; Watanabe, Masashi ; Machida, Masahiko

Brouwer's diagrams for PuO $_{2}$ and CeO $_{2}$ were constructed based on results of oxygen potential measurement and DFT calculation. Defect concentration, oxygen diffusion coefficient and electrical conductivity were evaluated, and differences between PuO $_{2}$ and CeO $_{2}$ were discussed.
