Zirconia materials are used in very high wear applications under very high pressure requiring improved fracture toughness and stiffness over alumina. Zirconia is noted for its high strength, toughness, wear and thermal properties. Its high material cost usually warrants its usage extending longer life and reduce down time where alumina fails in this applications.
During manufacture, the zirconia powder is combined with oxides such as Yttria, magnesia or tetragonal and the material is said to be partially stabilised or even it can be fully stabilised if required, varying the composition allows different properties to be enhanced.
