Oxygen Ion Conductivity Above

Yttria-stabilized zirconia is an excellent oxygen ion conductor used in oxygen and carbon sensors and offers excellent refractoriness at temperatures up to and above 2000°C

Zirconia (ZrO2) is an extremely refractory material. It possesses excellent chemical inertness and corrosion resistance at temperatures well above the melting point of alumina. McDanel Zirconia is stabilized in the cubic crystal structure to avoid cracking and mechanical weakening during thermal cycling. In addition to its high temperature capability, Zirconia offers low thermal conductivity and is electrically conductive above 800ºC. Also has the unique ability to allow oxygen ions to move freely through the crystal structure above 600ºC.

Standard McDanel Zirconia products include various single bore tubes that are available for purchase online. We also have significant capabilities for producing custom engineered Zirconia products.
