Mascera offers custom production for zirconia ceramic sleeves / tubes, 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 sleeves / tubes can be machined with diamond machining tools only. The ceramic sleeves / tubes are made of superfine raw powders and fully dense, a mirror surface could be achieved after fine grinding and polishing.

Product detail

Mascera specializes in custom production of zirconia ceramic sleeves/tubes. These sleeves/tubes are crafted from highly durable zirconia ceramic (ZrO2, Zirconium Oxide), known for its extreme hardness. With a hardness rating of up to Moh's grade 8.5, which is close to that of diamond (Moh's grade 10), zirconia ceramic sleeves/tubes require diamond machining tools for precise machining. Our ceramic sleeves/tubes are manufactured using superfine raw powders, resulting in fully dense structures. Through fine grinding and polishing, we can achieve a mirror-like surface finish.

Zirconia ceramic sleeves/tubes exhibit superior wear resistance, high strength, and excellent corrosion resistance. They are well-suited for use as structural parts, as their exceptional wear resistance greatly enhances their lifespan, reducing the need for frequent replacements and lowering associated costs. Furthermore, the low thermal coefficient of zirconia ceramic sleeves/tubes enables seamless assembly and compatibility with steel parts.

At Mascera, we offer zirconia ceramic sleeves/tubes in custom sizes and machining specifications. Our production capabilities allow us to achieve high accuracy, with tolerances of up to +/- 0.002mm. Additionally, surfaces can be polished to a roughness of Ra0.1μm. If desired, we can incorporate thread holes or external threads for convenient fastening purposes.

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.
