The effect of lutetium dopant on oxygen permeability of alumina polycrystals under oxygen potential gradients at ultra-high temperatures

Tsuneaki Matsudaira, Auteur ; Masashi Wada, Auteur ; Tomohiro Saitoh, Auteur |

Dans Acta materialia (Vol. 58 N° 5, Mars 2010)

The oxygen permeability of undoped and lutetia-doped polycrystalline alumina wafers that were exposed to oxygen potential gradients was evaluated at temperatures up to 1973 K. The main diffusion species during oxygen permeation through the alumi[...]
