Zirconia's exceptional strength and remarkable resistance to corrosion, wear, and abrasion make it an ideal material for various applications.
What is magnesium oxide partially stabilized zirconia ceramics？What is magnesium oxide partially stabilized zirconia ceramics？
The oxidase partially stable zirconia ceramics (MG-PSZ), commonly known as magnesium-zirconia ceramics, have a yellow color and a density of approximately 5.7 g/cm³.
Magnesium oxide is used as the stabilizer for zirconia in MG-PSZ, resulting in a more stable crystal structure. Magnesium zirconium exhibits superior resistance to high temperatures and moisture due to its immunity to phase migration. Even in humid and high temperature environments, where the mechanical properties of yttrium partially stabilized zirconia deteriorate, magnesium zirconium retains its strength.
Conventional zirconias typically contain metastable transformable particles, which necessitates the need for stabilization to prevent phase transformation. One way to achieve this is through the use of MgO partial stabilized zirconia (Mg-PSZ). In Mg-PSZ, a smaller amount of MgO stabilizer is added, enough to maintain a consistent cubic structure. The remaining portion of the zirconia undergoes transformation between monoclinic below and tetragonal above the transformation temperature. This unique composition results in significantly enhanced strength and resistance to temperature changes. Mg-PSZ offers a promising solution for applications requiring durable materials that can withstand varying thermal conditions.
