Novel wedge-geometry, dual-layer alumina samples, both undoped and 500 ppm Y 3+ -doped, were studied in the temperature regime 1250-1400 ยฐC to determine the effect of Y 3+ on oxygen grain-boundary transport in alumina. The samples consisted of a wedge-shaped, single-phase alumina top layer, diffusio
