An ion-microprobe study of the self-diffusion of Li+ of lithium fluoride
The self-diffusion coefficient of Li+ in lithium fluoride has been determined over the temperature range 650-800°C using the ion-microprobe analyser. The evaluation of the tracer diffusion coefficients for 6Li and 7Li from the intrinsic diffusion coefficient obtained under the non-tracer conditions...

| Zusammenfassung: | The self-diffusion coefficient of Li+ in lithium fluoride has been determined over the temperature range 650-800°C using the ion-microprobe analyser. The evaluation of the tracer diffusion coefficients for 6Li and 7Li from the intrinsic diffusion coefficient obtained under the non-tracer conditions of the ion-probe measurement is also discussed.

values in the Arrhenius equation are found to be 90·9 ± 0·6 and 85·7 ± 0·6 cm 2see-1 for 8Li and 7Li respectively, and the activation energy, 2·13 ± 0·02 eV. |
