Oxygen permeation characteristics of zirconia with surface modification
No full textYttria-stabilized zirconia (YSZ) can be used as an oxygen-permeating membrane at elevated temperature (> 1400 degrees C) due to its chemical and mechanical stability. It was previously shown that the oxygen transport through YSZ membrane in reducing oxygen partial pressure (Po-2) was highly influenced by the surface-exchange kinetics that can be improved by porous surface coating layers such as YSZ, GDC (Gd-doped ceria) or YSZ-GDC mixture [H.J. Park, G.M. Choi, J. Eur. Ceram. Soc. 25 (2005) 2577]. However, the increased oxygen flux was still lower than that estimated assuming bulk-diffusion limit and rapidly decreased with time due to the sintering of coating layers and the reaction between bulk YSZ and coating layers. In this study, the oxygen fluxes through YSZ with LaCrO3, GDC+LaCrO3 (bilayer), LaCrO3+5 wt.% GDC (mixture), or LaCr0.7CO0.3O3 coatings were measured under controlled PO2 gradient (permeate-side Po-2: similar to 3 x 10(-12) atm, feed-side Po-2: 2x10(-10)-2 x 10(-8) atm) at 1600 degrees C. The oxygen flux drastically increased with these coatings. The highest increase in oxygen flux was shown with GDC + LaCrO3 (bilayer) coating and was maintained for a long time. The presence of highly catalytic Ce ions while maintaining porous structure in the coating layer may explain the observation. The prevention of formation of resistive layer due to ceria coating may also be partly responsible for the observation. (c) 2006 Elsevier B.V. All rights reserved.X1112sciescopu
