Conclusions

A relation has been derived between the activation energy for self-diffusion and the characteristic temperature near the melting point for inorganic crystals having the NaCl structure, on the basis of a vacancy diffusion mechanism.

A simplified relation, (10), has been found for determining EA from a melting point. Carbon diffusion in carbides on the basis of structural vacancies has been discussed.
