Abstract
Gadolinium-doped ceria (CGO) presents unique processes at low oxygen partial pressure (pO2 < 10−12 atm) and low temperatures (T > 800 °C) such as faster mass diffusion, which are not observed in conventional sintering under ambient air conditions. These effects lead to fast elemental interdiffusion in ceria/alumina composites.
