Abstract
The effect of HfO2 on the structural and electrical stability of solid electrolytes based on tetragonal zirconia was studied. Long-term hold ing of HfO2-containing ceramics at 450 degrees C was found to lead to the formation of a monoclinic solid solution. As a result, the conduct ivity of the ceramics decreases, primarily because of an increase in g rain-boundary resistivity.
