Zirconia Ceramic:
Zirconium oxide is a special material, and the method of toughening is mainly achieved by the phase transformation of zirconia!
Pure zirconia is a white solid that appears gray or yellowish when it contains impurities, and can be displayed in a variety of other colors by adding a developer. Pure zirconia has a molecular weight of 123.22, a theoretical density of 5.89 g/cm3, and a melting point of 2715 °C. It usually contains a small amount of cerium oxide, which is difficult to separate, but has no significant effect on the properties of zirconia. Zirconia has three crystal forms: monoclinic, tetragonal, and cubic. At room temperature, zirconia appears only in a monoclinic phase, and is heated to a tetragonal phase when heated to about 1100 ° C. When heated to a higher temperature, it is converted into a cubic phase. Due to the large volume change during the transition of the monoclinic phase to the tetragonal phase, a large volume change occurs in the opposite direction during cooling, which easily causes cracking of the product, which limits the application of pure zirconia in the high temperature field. . However, after the addition of the stabilizer, the tetragonal phase can be stabilized at normal temperature, so that no volume change occurs after heating, which greatly expands the application range of zirconia. The raw material used as a stabilizer in the market is mainly cerium oxide.
