Substitutional Solid Solutions

Factors for high solubility:

• Atomic size factor - atoms need to “fit” ⇒ solute and solvent atomic radii should be within ~ 15%

• Crystal structures of solute and solvent should be the same

• Electronegativities of solute and solvent should be comparable (otherwise new inter-metallic phases are encouraged)

• Generally more solute goes into solution when it has higher valency than solvent
