ZrO{sub 2} doped with various compositions of two stabilizers, Y{sub 2}O{sub 3} and MgO, in order to lower sintering temperature and improve the electrical behavior of sintered bodies have been investigated in this study. The results show that densification of Y{sub 2}O{sub 3}-ZrO{sub 2} system is enhanced by MgO addition. Sintered bodies display a bimodal distribution of grains under proper addition. This research discovers that (YO{sub 1.5}){sub 0.08}(MgO){sub 0.04}(ZrO{sub 2}){sub 0.88} system has high conductivity and responsible oxygen sensitivity. With regard to oxygen sensitivity, the log behavior EMF takes place a 440 and 550{degrees}C. Besides, the EMF decreases at a very low oxygen pressure caused by electronic conduction and electrode polarization. 31 refs., 7 figs., 3 tabs.
