| Some regularities of interactions of palladium with periodic table elements were summarized, and the solid solubilities of periodic table elements in palladium were analyzed by the classical solid solubility theory and Miedema’s bond parameters. A solubility equation, lnCmax =4.6052–k (|Δnws1/3|– nR), was established, the limit solid solubility (lnCmax), of solutes in palladium increases with the electron density difference, |Δnws1/3|, between them. The solid solubilities of the simple metal solutes in palladium are larger than those of transition metal solutes with same Δnws1/3 based on different solubility mechanisms. The relationship of solvability ability indexes of precious metals as solvents with their electron density nws1/3 were analyzed by their electron density parameters nws1/3, and the palladium solvent has the largest solubility ability index for periodic table elements as solutes. |
