Abstract
This paper gives the available data for the maximum equilibrium solubility limits of each of the first 83 elements (H to Bi) of the periodic table in each of the others. This is expressed in the form of the maximum value of the equilibrium solid solubility for terminal solid solutions, expressed in atomic percentage (at%), occurring at any temperature where the room temperature phase of the pure element acting as the solvent is stable. The values thus represent the compatibility between different elements in the formation of alloys and similar combinations, and will be of use for research into fundamental solid state physics relating to elemental interactions, for the interpretation of phase structures in materials research and for the design of alloys and materials involving elemental mixing of the elements.
