Zirconia is most famous high-performance material among all oxide ceramics. Ceramic components made out of Zirconia generally consist of Zirconia as basic material doped with some percentage of other oxides like Yttria (Y2O3) or Magnesia (MgO). Depending on doping material different material properties could be achieved because of influencing the Yttria's microstructure. The "ceramic steel" titled Zirconia is doped with Yttria forming an ultra-fine ductile structure with sub-micron grain formation leading to enormous bending strengths. Magnesia doped qualities are less strong also showing a coarser microstructure.
Common applications of Zirconia ceramics include extrusion dies, wire and pipe extension, guide and other wear rollers, pressure valves, and bearing materials.
