- I am not too much familiar with ZrO2, but I know its electrical
- properties are complicated. Mostly it is an ionic conductor. Being
- a non-stoichiometric material, it conducts via oxygen ion transpor-
- tation. Some doped zirconia (e.g., Yittrium or Cerium doped) are
- mixed conductor and point defects (such as vacancies) play an
- important role to determine its electrical properties.
-
- I heard ZrO2 is used in some oxygen sensors, the ones that are
- used at higher temperatures.
