抄録

A solution of the flux density equation is presented for grain−boundary enhanced diffusion in a polycrystalline system when the penetration depth is large relative to the grain size. The solution is applied to interdiffusion between 13 and 19 mol% CaO-stabilized zirconia polycrystals from 1375–1650 °C. Lattice interdiffusion coefficients calculated from the concentration distributions are slightly larger than the previously reported self-diffusion coefficients of the individual cations.
