Hg-Pd (Mercury-Palladium) C. Guminski The assessed phase diagram is based mainly on the experimental data of [65Jan] and [75Gal]. By extrapolating experimental data, the corresponding solubility of Pd in Hg at 357 C should be 1.1 at.% Pd [86Gum]. An extrapolation of the data to temperatures lower than 25 C would lead to imprecise values and is not recommended. This region of the liquidus needs further investigation. The Pd- rich part of the liquidus at a constrained Hg vapor pressure is unknown. The solid solubility of Pd in (Hg) appears to be negligibly small. The solubility of Hg in (Pd) was investigated by [61Ter], who reported a value of 13.8 at.% Hg at room temperature. It is assumed that this value will not change much at higher temperatures. 52Bit: H. Bittner and H. Nowotny, Monatsh. Chem., 83, 287-288 (1952) in German. 61Ter: K. Terada and F.W.
