Abstract
A numerical technique for predicting the kinetics of demixing of oxide solid solutions in an oxygen chemical potential gradient is presented. The unique advantage of this technique is that it permits handling of transient state conditions, variable diffusion coefficients, and variable boundary conditions. Solutions obtained by this technique agree very well with the steady-state kinetics predicted by analytical methods.
