Abstract
In this paper, a concept, the chemical potential of vacancies in metal crystals, has been derived from the partial mole free energy of vacancies, based on a model of an atom-vacancy binary solution. For a pure metal crystal containing the mole concentration of vacancies, Cy and it's value in thermal equilibrium, Co, at temperature T, the chemical potential can be expressed respectively as: μ(Cv) = RT[1 + 1n(Cv/Co)] and μ(Co) = RT The second term in μv (Cv) is the chemical potential of the vacancies referred to the standard-state concentration given by J. P. Hirth[1] and first term is the standard-state one presented.
