Research output: Contribution to journalArticlepeer-review


Nanometer zirconia ultrafine powders stabilized with scandia were prepared by chemical co-precipitation. The powders and their sintered specimens were studied by means of XRD, TEM, SEM and BET specific surface area techniques. It shows that zirconia powders stabilized with 6.0mol%, 7.8mol% and 9.6mol% scandia have good sinterability, while the specimens stabilized with 3.5mol% and 12.0mol% scandia are softly sintered, which is attributed to the existence of dual microstructure and the volume change resulting from phase transitions when the specimens are cooled from sintering temperature. In order to obtain Zirconia solid electrolyte composed of simple and stable phases, the content of scandia near 7.8mol% should be selected.
