Following the inconsistencies experienced when adding the NaK via aqueous solution, a new approach was taken: adding the hydroxides in a powder form and weighing/combining the ceramic powders and transport phase in a dry (1% RH) glovebox environment. This method posed its own challenges, primarily difficulties in even distribution of the hydroxide powders among the ceramic parent powder. However, the use of the dry glovebox and hydroxide powders made possible the study of the impact of water on the HAD technique using the NaK transport phase, in addition to improving experimental reproducibility. Given the proven dependence on water content and the nonequilibrium state of HAD (i.e., high pressures in a semi-sealed system), baseline experiments were conducted to investigate the properties of the NaK transport phase itself.
