Electrical and mechanical properties of CeO2-based electrolytes in the CeO2–Sm2O3–M2O3 (M = La ,Y) system
2008
Abstract Samples of Ce 0.8 Sm 0.2 O 2 and Ce 0.8 Sm 0.2 − x M x O 2 (M = La, Y and 0 x − 2 –10 7 Hz are also presented and discussed. The electrical properties of the ceria samples co-doped are found to be improved. The best oxygen-ion conductivity was found for Ce 0.8 Sm 0.1 Y 0.1 O 2 compound. Testing results of this compound used as an electrolyte in oxygen-ion concentration cell are also reported.
