Abstract. By using a thermodynamical model, the activation entropy is extracted from the experimental diffusion data of Al in MgO. Furthermore, we estimate the activation volume. We find a value for the activation entropy of (4.21 ± 0.05) k. As for the activation volume, we calculate the value (3.65 ± 0.16) cm3 mol −1 which is comparable with the experimental values when errors are considered.
