Advanced Mg-Psz MGO Partially Stabilized Magnesia-stabilized Zirconia Ceramic fixture

Magnesium-stabilised zirconia ceramics use magnesium oxide (MgO) as a stabilising agent for zirconia, and the crystal structure is cubic lattice after moulding, which is more stable. Magnesia-zirconia has better resistance to high temperature and humidity because it is not affected by phase migration. Magnesia-zirconia retains its strength even in humid, high-temperature environments where the mechanical properties of yttrium oxide partially stabilised zirconia begin to deteriorate.

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.

This exceptional stability makes MG-PSZ an ideal material for applications in harsh conditions. Its resistance to phase migration ensures that it can maintain its structural integrity even when exposed to extreme temperatures and moisture. This is particularly advantageous in industries such as aerospace and automotive, where components are subjected to demanding environments. The yellow color of MG-PSZ also adds aesthetic appeal, making it a popular choice for decorative purposes.

Furthermore, the density of approximately 5.7 g/cm³ makes MG-PSZ lightweight yet durable. This combination of properties makes it highly versatile, suitable for a wide range of applications. Whether it's used in engine components, cutting tools, or even jewelry, MG-PSZ offers exceptional performance and reliability.

In conclusion, the unique properties of MG-PSZ, including its stability, resistance to high temperatures and moisture, and lightweight nature, make it a valuable material in various industries. Its yellow color and density further enhance its appeal, making it a sought-after choice for both functional and decorative purposes.
