3 mole% Y2O3 (5.35 wt%). CERAFLEX is a sintered and fully dense zirconia ceramic material that is formed into extremely thin sheets, that are both flexible and highly resilient. The high strength of CERAFLEX makes it easier to handle than other ceramic materials of the same thickness. CERAFLEX is available as strips, sheets, or custom parts. It is either partially or fully stabilized with yttria.

The fully stabilized material is an oxygen ion conductor and used to build solid oxide fuel cells and oxygen sensors. A new cesium stabilized material (CERAFLEX:Cs) with much better electrical conductivity is now available.
