Abstract
The electrolyte comprises up to about 80 wt % zirconia, up to about 30 wt % stabilizer, and up to about 40 wt % dopant-zirconia. Alternatively, the electrolyte can comprise zirconia having a phase chemistry, wherein the phase chemistry, at about 25° C., is about 15 wt % to about 35 wt % monoclinic, less than about 10 wt % tetragonal, balance cubic, based upon the weight of the zirconia in the electrolyte.
