Product Code : CE-ZrO2-5N-BR
Dubbed ‘ceramic steel’, Zirconia (Zro2) ceramic offers a combination of high hardness, wear and corrosion resistance, while exhibiting one of the highest fracture toughness values among all ceramic materials. There are several grades of Zirconia available –, the most common of which are Yttria Partially Stabilized Zirconia (Y-PSZ) and Magnesia Partially Stabilized Zirconia (Mg-PSZ). Both of these materials offer excellent properties. However, the operating environment and design will dictate which grade may be suitable for specific applications. Its high thermal expansion and unique resistance to crack propagation make it an excellent material for joining with metals like steel.
Zirconia rod has the advantages of super hardness, high wear-resisting, good corrosion resistance, high-temperature tolerance, high strength, high mechanical strength, good chemical stability, polishing surface, and so on.

· Magnesia Stabilized Zirconia (MSZ) – magnesia stabilized; for high-temperature applications; it is not vulnerable to phase transformations at elevated temperatures; heterogeneous microstructure to protect against grain boundary sliding; transformation toughened; high fracture toughness
· Yttria Stabilized Zirconia (YTZP) – yttria stabilized; fine-grained microstructure predominantly tetragonal phase; extremely high strength and toughness; use temperatures below 500°C; transformation toughened to resist crack propagation; superior chemical resistance; excellent wear resistance
· Ceria Stabilized Zirconia (CSZ) – ceria stabilized high temperature, as well as high or low pH environments; transformation toughened; maintains strength in steam and pressure conditions; ceria fills crystal structure vacancies to prevent low temperature degradation
· Zirconia Toughened Alumina (ZTA) – zirconia toughened alumina; provides 20-30% greater strength than alumina at a lower cost than stabilized zirconias. Transformation toughened; Higher toughness, hardness and wear resistance than alumina
Advantages

Zirconia Machining
Zirconia can be machined in green, biscuit, or fully dense states. While in the green or biscuit form, it can be machined relatively easily into complex geometries. However, the sintering process that is required to fully densify the material causes the zirconia body to shrink approximately 20%. This shrinkage means that it is impossible to hold very tight tolerances when machining zirconia pre-sintering. In order to achieve very tight tolerances, the fully sintered material must be machined/ground with diamond tools. In this manufacturing process, a very precise diamond coated tool/wheel is used to abrade away the material until the desired form is created. Due to the inherent toughness and hardness of the material, this can be a time consuming and costly process.
Applications of Zirconia Rod

Packing of Zirconia Rod
Standard Packing:
Sealed bags in carton boxes. Special package is available on request.
As a ceramic material, ZrO2 is quite fragile in a lot of cases. The ZrO2 rod are usually held in plastic bags by vacuum, and protected with heavy foam.
ATTs’ ZrO2 rod is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
