Pure 8YSZ and ZnO doped YSZ ceramics are prepared using the solid state reaction method sintered at 1550°C for 2 hours. The X-ray Diffraction (XRD) results reveal the presence of tetragonal, cubic and monoclinic phase of Zirconium dioxide (ZrO2) for all undoped and doped YSZ sintered samples. The phase stability of tetragonal YSZ was found to be increased with the increase in ZnO addition. Minor fraction of monoclinic phase was found in pure YSZ sintered sample and the amount of monoclinic phase decreased with the increasing amount of Zn after sintering at 1550°C for 2 hours. The fraction of cubic phase was also found to decrease with the increase in Zn concentration. The highest ionic conductivity of 1.03×10−3 S cm−1 was obtained at room temperature for samples with 3 mol% ZnO. Pure 8YSZ sintered sample on the other hand, yielded 9.88x10−4 S cm−1. 2020-12-30T03:07:04Z 2020-12-30T03:07:04Z 2016 Article MATEC Web of Conferences, vol.78, 2016, 8 pages 2261-236X (online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/69172 https://doi.org/10.1051/matecconf/20167801101 en 2nd International Conference on Green Design and Manufacture 2016 (IConGDM 2016); EDP Sciences
