“…Critical analysis of the available hydrogen solubility data obtained by Sieverts' technique must consider the following information: Helium is recognized as the best reference gas from hydrogen solubility measurements with the Sieverts' technique, as its thermal conductivity and its kinematic viscosity are similar to those of hydrogen. [45][46][47][48][49][50][51] Note that the thermal conductivity and the kinematic viscosity greatly affect the heat transfer in the gas phase, [47] thus influencing the temperature gradient inside the hot volume. To remove the influence of the temperature gradient inside the absorption bulb on the evaluation of the hot volume, the reference gas must behave as close as possible to hydrogen.…”

The modeling of hydrogen solubility in multicomponent Al-(Li, Mg, Cu, and Si) liquid phase has been performed with a thermodynamic approach using the modified quasichemical model with the pair approximation (MQMPA). All hydrogen solubility data available in literature was assessed critically to obtain the binary parameters of the MQMPA model for the Al-H, Li-H, Mg-H, Cu-H, Zn-H, and Si-H melts. For the Li-H system, a new thermodynamic description of the stable solid lithium hydride was determined based on the c p found in literature. The thermodynamic model for the Al-Li system also was reassessed in this work to take into account the short-range ordering observed for this system. Built-in interpolation techniques allow the model to estimate the thermodynamic properties of the multicomponent liquid solution from the liquid model parameters of the lower order subsystems. A comparison of the calculated hydrogen solubility performed at various equilibrium conditions of temperature, pressure, and composition with the available experimental data found in the literature is presented in this work, as well as a comparison with some results from previous modeling.

“…where k He is the thermal conductivity of Helium [27], d is the height of the sapphire window, T 1 is the ambient temperature and r SB is the Stefan Boltzmann's constant. The high pressure buffer gas is assumed to suppress mass vapourization of UO 3 to inhibit a stoichiometry change in the sample.…”
