Diffusivity of T in Be
$$
D = D_0 \exp\left(-\frac{E_\mathrm{d}}{k_\mathrm{B}T}\right)
$$
[In the above formula, the Boltzmann constant is expressed in \(\mathrm{eV\,K^{-1}}\).]
- Material: Be
- Method: Experiment
- Data scaled for isotope mass? No
- D0 = 0.0001 m2 s-1
- Ed = 1.85 eV
- T = 900 – 1500 K
