Zirconia has been also used to form many different structural components. By adding small amounts of lime, yttrium, or magnesia, a partially stabilized zirconia (PSZ) ceramic is formed. In doing so, precipitates of tetragonal and/or monoclinic phases are dispersed in a cubic zirconia matrix. PSZ zirconias have enhanced mechanical properties allowing high-strength, structural components to be manufactured.

Due to zirconia's wear and corrosion resistance, it can be considered as a good refractory material for handling molten metals. Some examples would be crucibles for aircraft alloys, and nozzles and slide gates used in the continuous casting of steels.

Zirconia ceramics's high strength and toughness makes it an excellent candidate for applications such as extrusion dies, grinding media, ceramic liners, cutting tools valve seats, guides, engine parts and medical implants.

Zirconia's excellent ionic conductivity, which is present in the cubic form, can be considered for applications like oxygen sensors and fuel cells.
