ON THE CALCULATION OF POINT-DEFECT EQUILIBRIA

A method is outlined for solving the equations describing the quasi chemical equilibria of point defects, with particular reference to binary oxides. The method gives exact solutions for all defect concentrations and the oxygen activity as a function of n = [e']. In comparison to the traditional approach, the feasibility of the method does not depend on the number of differently charged defects of the same kind. Possible extensions of the approach are briefly discussed.
