Modeling the mechanism of interaction of defects is in CeO2-x at high temperatures in air
The consequent of mathematical models with elements of theory probability and experimental results, calculations permitted to determinate the energy formation of: anion vacancies (uв∼0.9 eV), border and screw dislocations (u⊥∼ 1.67 eV; us ∼ 2.08 eV), and the energy of movement point defects (ud∼ 1.8...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The consequent of mathematical models with elements of theory probability and experimental results, calculations permitted to determinate the energy formation of: anion vacancies (uв∼0.9 eV), border and screw dislocations (u⊥∼ 1.67 eV; us ∼ 2.08 eV), and the energy of movement point defects (ud∼ 1.8 eV) and of movement the borders grain (uз ∼ 0.65 eV), strain which were connected with cooperation action point defects with admixture (0.25 eV – energy of formation center painting) in CeO2 – x at high temperatures in air. The evaporation and disintegration harden solution on the base CeO2 – x were determinate on the base obtained facts the next structure cubic phases F – F1 – C. The process oxidation at 1500 °C accompanied of disappear the border, spiral dislocations and point defects. |
