Zirconia ceramics have different physical and chemical properties

In practical applications, in order to obtain the required crystal form and performance, different types of stabilizers are usually added to make different types of zirconia ceramics, such as partially stabilized zirconia (PSZ), when the stabilizers are CaO, MgO, In the case of Y2O3, they are respectively expressed as Ca-PSZ, Mg-PSZ, Y-PSZ, etc. The tetragonal zirconia composed of metastable t-ZrO2 is called tetragonal zirconia polycrysta (TZP). When the added stabilizers are Y2O3 and CeO2, they are expressed as Y-TZP, Ce-TZP, etc. respectively.
