| Zusammenfassung |
Analytical formulas for the temperature dependence of elastic constants of
MgO combined with a thermodynamic model, which interconnects bulk properties
to point defect parameters, can successfully reproduce the self diffusion
coefficients of periclase at temperatures representative of the Earth's
mantle conditions.
Although the calculated diffusion coefficients are estimated from a single
measurement and cover a broad range of values (i.e. five orders of
magnitude), an almost excellent agreement with the experimental ones is
observed. The slight discrepancy at the highest temperature lies at error
margins. |
