While several types of oxygen sensors have been investigated for automotive use, the most common type in commercial use consists of a galvanic cell with a fully or partially stabilized zirconium oxide electrolyte. 

Single oxide ceramics, e.g. aluminium oxide (AI2O3, alumina) and zirconium dioxide (Zr02, zirconia), are bioceramics of an inert nature. An inert ceramic does not form a bonding to bone similar to those bioceramics of bioactive nature. Alumina bioceramics are in the pure aluminium oxide form, whereas zirconia bioceramics are partially stabilized by additional oxides, e.g. yttrium oxide, calcium oxide or magnesium oxide. 

The partially oxidized TiC y also had superior catalytic activity for the ORR [104]. The onset potential of the appropriate oxidized ZrC cN reached 0.97 V vs. RHE in 0.1 M H2SO4 at 30°C. In particular, resource of zirconium oxide, 51 X 10 kton, is three orders of magnitude greater than that of platinum, 39 kton. Therefore, zirconium oxides might be a good candidate for the nonprecious metal cathode of PEFCs, considering both its stability and amount of resources.

Zirconium oxide, stabilized with 3-8% YjO, also has been used in k-probes for determination of the partial pressure of oxygen in car exhaust fumes that makes it possible to optimize the air-fuel mixture to the engine. A similar solid electrolyte is used as a probe for determining oxygen in molten steel. 

Powders of partially stabilized zirconium dioxide-yttrium oxide ceramics (PSZs) were prepared at room temperature and under nitrogen at atmospheric pressure by hydroiysis of zirconium and yttrium alcoholates solutions containing a carboxyiic acid.
