Wear Resistant Industrial Zirconium Oxide Zirconia Ceramic Ring
- MSJ/ZR-014
- zirconia ceramic
- customized
- 10 pcs per type
- wear resistant ceramic parts
Mascera offers custom production for zirconia ceramic rings, they are made of extreme hard zirconia ceramic (ZrO2, Zirconium Oxide), the hardness is up to Moh's grade 8.5 which is very close to that of dimond (Moh's grade 10), therefore zirconia ceramic rings can be machined with diamond machining tools only. The ceramic rings are made of superfine raw powders and fully dense, a mirror surface could be achieved after fine grinding and polishing.

Product detail
Mascera offers custom production for zirconia ceramic rings, they are made of extreme hard zirconia ceramic (ZrO2, Zirconium Oxide), the hardness is up to Moh's grade 8.5 which is very close to that of dimond (Moh's grade 10), therefore zirconia ceramic rings can be machined with diamond machining tools only. The ceramic rings are made of superfine raw powders and fully dense, a mirror surface could be achieved after fine grinding and polishing.
Zirconia ceramic rings have superior wear resistance, high strength and excellent corrosion resistance. They are durable enough to use for structural parts, the superior wear resistance of zirconia ceramic will greatly improving the working life and reduce the replacement frequency and cost. The low thermal coefficient enables zirconia ceramic rings to have good assembling and fittings with steel parts.
Mascera could produce zirconia ceramic rings in required sizes and machining requirements. The best accuracy we can achieve is up to +/-0.002mm and surfaces could be polished to a roughness of Ra0.1μm. We can produce zirconia ceramic rings from a small size to a maximum diameter of 400mm, welcome to contact us for your specific requirements.
Types of Zirconia Ceramics
Mascera has 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 will have transformation of crystal structure when temperature reaches the certain value, the volume changes drastically when the crystal phase changes, and the finished parts after sintering will crack. To provent this problem, stabilizing agent like Yttrium oxide (Y2O3) or Magnesium oxide (MgO) are doped into zirconia ceramic by changing the crystal structure from a monoclinic to stable tetragonal phase.
Both Y-PSZ and Mg-PSZ have excellent mechanical properties such as high hardness, high mechanical strength, good wear resistance and good corrosion resistance in room temperature. The difference is that Mg-PSZ has better strength in mosit and high temperature environment while the mechanical properties of Y-PSZ begin to deteriorate.
Main properties of zirconia ceramic rings
