An advanced zirconia ceramic stabilized with magnesium oxide, developed for high-temperature service, thermal shock resistance and demanding industrial environments. Mg-PSZ is particularly suited to metallurgy, steel production, petrochemical equipment and precision mechanical components.

Magnesia Partially Stabilized Zirconia, commonly abbreviated as Mg-PSZ, is an advanced oxide ceramic made by stabilizing zirconia with magnesium oxide. According to the material information provided by VANCERA, zirconia containing approximately 8–12 mol% magnesium stabilizer is classified as magnesia partially stabilized zirconia.
Zirconia ceramics are valued for their high melting point, hardness, low thermal conductivity, low friction and chemical inertness. Mg-PSZ is especially noted for its high-temperature performance and resistance to thermal shock.
With a listed maximum working temperature of 2,000°C, Mg-PSZ is used in demanding industrial environments where components must withstand substantial heat and challenging operating conditions.
Mg-PSZ combines the characteristic properties of zirconia with magnesium stabilization, making it a candidate material for high-temperature equipment and demanding mechanical applications.
Mg-PSZ is designed for elevated-temperature environments. The VANCERA material data lists a maximum working temperature of 2,000°C.
Its reported thermal shock resistance of 250°C makes the material relevant to applications involving significant temperature changes.
With a listed bending strength of 500 MPa and compressive strength of 2,500 MPa, Mg-PSZ can support demanding mechanical service conditions.
A Vickers hardness value of 1,200 HV 0.5 indicates a hard ceramic surface for applications where resistance to surface damage is important.
The listed thermal conductivity is below 2 W/mK, a characteristic relevant to thermal management and high-temperature component design.
Zirconia ceramics are known for their high melting point, low friction, chemical inertness and useful electrical properties. Actual performance depends on operating conditions and component design.

Note: Values are representative engineering data reproduced from the referenced VANCERA Mg-PSZ page. The source describes the material's working temperature as higher than 2,000°C in its text, while the property table lists 2,000°C as the maximum working temperature. Confirm the applicable temperature limit with the supplier for the intended service conditions. The source labels the 7 MPa·m¹ᐟ² property as “Shock Strength”; this page retains that original label rather than treating it as a verified fracture-toughness value. Electrical properties shown as “-” and chemical test data are not specified in the source. Actual properties may vary with manufacturing method, component size, shape and test conditions.
