Properties of Zirconia ZrO2  

Zirconia (ZrO2) is an extremely refractory material. It possesses excellent chemical inertness and corrosion resistance at temperatures well above the melting point of alumina. Innovacera Zirconia is fully 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.
