Magnesia
partially stabilized zirconia ceramics, also known as Mg-PSZ ceramics, are a
type of ceramic material that is composed of partially stabilized zirconia
(PSZ) with the addition of magnesia (MgO).
Zirconia (ZrO2) is a ceramic material that has
excellent mechanical properties, such as high strength and hardness, as well as
good resistance to wear and corrosion. However, pure zirconia is prone to
cracking and low-temperature degradation. To overcome these limitations,
zirconia can be partially stabilized by adding certain dopants, such as yttria
(Y2O3), calcia (CaO), or magnesia (MgO).
Magnesia partially stabilized zirconia
ceramics have a microstructure consisting of small, well-dispersed zirconia
grains embedded in a magnesia matrix. The addition of magnesia helps to improve
the stability and toughness of the material, making it more resistant to
cracking and low-temperature degradation. This makes Mg-PSZ ceramics suitable
for a w…
