$TiO_2$ 를 첨가한 안정화 지르코니아의 전기전도특성
Electrical Conductivity Characteristics of Stabilized Zirconia added with Titania
초록
The microstructure and electrical conductivity characteristics were examined for the Yttria Stablized Zirconia that were added Titania with the concentration of 0.02wt%, 0.05wt% and 0.1wt%. The stabilized cubic phase had not been changed. The obtained density of the sintered body was higher than 97% of the theoretical density as the grain growth and proe removal. And the highest density of 5.91g/cm**3 was obtained for 0.02wt% addition of TiO2. When 0.02 wt% TiO2 was added to YSZ, the electrical conductivity was 0.293.(\ulcorner.cm)**-1 and the limit of electrolyte regime Pn was 4x10**-28 atm. at 1, 100\ulcorner, respectively. Those were improved value compared with the electrical conductivity 0.107 (\ulcorner.cm)**-1 and Pn 1.5x10**-27atm. without adding TiO2.
