Product detail
Zirconia ceramic (ZrO2, Zirconium Oxide) is an excellent choice for structural parts in various industries. It possesses a relatively high fracture toughness compared to other technical ceramics, which helps to overcome the inherent brittleness of ceramics. Zirconia ceramic also exhibits exceptional hardness, mechanical strength, and wear resistance at room temperature, greatly extending the service life of components.
One advantage of zirconia ceramic is its close coefficient of thermal expansion to steel, allowing for a good match between zirconia ceramic parts and steel parts. Compared to alumina ceramic, zirconia ceramic has a finer texture, and after grinding and processing, the surface finish can be exceptionally smooth, even achieving a mirror-like effect. This smooth surface finish reduces friction and enhances performance.
Zirconia ceramic finds wide application in structural ceramic parts and wear-resistant components, such as ceramic valve components, ceramic utility blades, ceramic grinding media, ceramic pump plungers, and ceramic bearings. Industries that benefit from zirconia ceramic include machinery, automotive, medical, petroleum, chemical, biological, and electronic communications.
Types of Zirconia Ceramics
Mascera offers two types of zirconia ceramic in our product range: Yttria Partially Stabilized Zirconia (Y-PSZ) and Magnesia Partially Stabilized Zirconia (Mg-PSZ). Pure zirconia ceramic undergoes a transformation of its crystal structure at a specific temperature, resulting in a significant change in volume and the potential for cracking in finished sintered parts. To address this issue, stabilizing agents such as Yttrium oxide (Y2O3) or Magnesium oxide (MgO) are added to the zirconia ceramic, effectively changing its crystal structure from monoclinic to a stable tetragonal phase.
Both Y-PSZ and Mg-PSZ exhibit excellent mechanical properties at room temperature, including high hardness, impressive mechanical strength, good wear resistance, and corrosion resistance. However, it is worth noting that while Mg-PSZ demonstrates better strength in moist and high-temperature environments, the mechanical properties of Y-PSZ can begin to deteriorate under similar conditions.
