The solubility of hydrogen,deuterium and tritium in liquid lead-lithium alloys

The solubility of H₂, D₂ and T₂ in liquid Pb-Li alloys was calculated, as a function of composition and temperature, using the thermodynamic data of the binary systems. In the 17 at% Li alloy, at 600 K the D₂ solubility is log K = ?4.20 ± 0.076, K in appm. torr^{?$\text{1}\text{2}$}, that of H₂ is ?4.125 ± 0.076, and that of T₂ is ?4.244 ± 0.076. The calculated values give a much lower solubility than the experimental data. A ternary H-Li-Pb interaction term must be postulated to get agreement between experimental and calculated results.
