Solubility of T in Be
$$
K_\mathrm{s} = K_\mathrm{s0}\exp \left(-\frac{E_\mathrm{s}}{k_\mathrm{B}T}\right)
$$
[In the above formula, the Boltzmann constant is expressed in \(\mathrm{eV\,K^{-1}}\).]
- Material: Be
- Material composition: 99.80%

Comment
Solubility increases (exothermic behaviour); this might be due to traps, see Wampler1984. Data provided by M. Lavrentiev (UKAEA, 2024) with permission from STEP.
