---------------------------------------------

	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.
