Mascera specializes in custom production of zirconia ceramic rods. These rods are crafted from extremely hard zirconia ceramic (ZrO2, Zirconium Oxide) known for its exceptional hardness, reaching up to Moh's grade 8.5, which is closely comparable to diamond (Moh's grade 10). As a result, zirconia ceramic rods can only be machined using diamond machining tools. Our ceramic rods are manufactured using superfine raw powders, ensuring a fully dense structure, and can achieve a mirror-like surface finish through meticulous fine grinding and polishing processes.

Product detail
Mascera specializes in custom production of zirconia ceramic rods. These rods 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 rods require diamond machining tools for precise machining. Our ceramic rods are manufactured using superfine raw powders, resulting in fully dense structures. Through fine grinding and polishing, we can achieve a mirror-like surface finish.
Partially Stabilized Zirconia (PSZ) components are more expensive than alumina and other oxide ceramics, but they offer unique properties such as extremely high fracture toughness, high thermal expansion, high flexural strength (MOR), and low thermal expansion. Due to their high fracture toughness and MOR, PSZ components resist crack propagation, are less brittle, and are capable of holding a sharp edge. PSZ components also act as thermal insulators, and their high thermal expansion makes it easier to join metal to steel, thanks to their low thermal conductivity. Some typical applications of PSZ components include knives, guides, and pump and valve components used in abrasive solutions and slurries.Furthermore, the low thermal coefficient of zirconia ceramic rods enables seamless assembly and compatibility with steel parts.
At Mascera, we offer zirconia ceramic rods 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 external threads on both ends of the ceramic rods 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.
