The yttrium doping effect on grain boundary diffusion was directly estimated using bicrystal experiments. For this purpose, pristine and yttrium-doped a-Al 2 O 3 bicrystals with the same geometrical configuration were fabricated. The grain boundary oxygen diffusion coefficients were measured by the
