(a) Decreasing silver content of AgPd crucibles with increasing run duration due to evaporation under open-system conditions (step-1 experiments). (b) In contrast, the Ag content is independent of the run duration under closedsystem conditions (step-2 experiments), because no evaporation takes place within the evacuated silica-glass ampoules. The Ag contents are means from single values recorded along a profile through the side wall of a crucible (Fig. 4). Symbols combined with a cross signalize crucibles with thicker walls (600 instead of 300 μm). The run durations are cumulated over several experiments.
