Enthalpy of activation for self-diffusion of inorganic substances having the NaCl structure

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 E_A from a melting point. Carbon diffusion in carbides on the basis of structural vacancies has been discussed.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 9, pp. 147–150, September, 1969.
