On the basis of chronopotentiometric measurements, the activation energy for O2- diffusion in the melts, for temperatures ranging from 410 to 510C, was estimated to be equal to 13kcal/mol. The diffusion coefficients varied from 1.6 x 10-5cm2/s at 400C, to 7.2 x 10-5cm2/s at 510C. V.I.Shapoval, V.A.Vasilenko: Ukrainski Khimicheski Zhurnal, 1974, 40[8], 868-71
