MONOCLINIC Sr1-xAxSi1-yGeyO3-0.5x, WHEREIN A IS K or Na, OXIDE ION CONDUCTOR |
| 摘要 |
The disclosure provides a material with the general formula Sr1-xAxSi1-yGeyO3-0.5x, wherein A is K or Na, including mixtures thereof, and wherein 0<y<l and 0<x<0.4. In a specific embodiment, 0<y<0.5. In another specific embodiment, 0<y<0.1 and 0<x<0.4. In another specific embodiment 0.9<y<1 and 0<x<0.25. The material may be a single-phase polycrystalline solid having a monoclinic crystal structure. The material may have an oxide-ion conductivity (&sgr;0) greater than or equal to 10-2 S/cm at a temperature of at least 500 °C. The material may be formed into a membrane or sheet or a composite with another solid member. The material may be used as the electrolyte in a fuel cell or a regenerative or reverse fuel cell, as an oxygen sensor, or as an oxygen separation membrane. The material may also be used as a catalyst for oxidation of an olefin or for other purposes where oxide -ion conductivity is beneficial. |
