High-performance zirconia ceramic engineered for excellent fracture toughness, high mechanical strength, outstanding hardness and reliable dimensional performance. 3Y-TZP is a tetragonal zirconia polycrystal with a balanced combination of mechanical properties for demanding room-temperature applications.
Yttria Stabilized Zirconia is a zirconium oxide ceramic modified with yttria (Y₂O₃) to improve and control the properties of zirconia. The amount of stabilizer is selected according to the performance requirements of the application.
Zirconia containing approximately 2–4 mol% yttria is known as Tetragonal Zirconia Polycrystal (TZP). Within this material family, 3Y-TZP is recognized for its excellent combination of mechanical properties at room temperature. Its outstanding fracture toughness has earned it the name "ceramic steel."
VANCERA's published 3Y-TZP data lists a density of 6.02 g/cm³, bending strength of 800 MPa and Vickers hardness of 1,150 HV 0.5. These characteristics make it a candidate material for demanding precision ceramic components.
3Y-TZP stands out among engineering ceramics for its combination of toughness, strength and hardness. These properties make it suitable for components that need to withstand demanding mechanical conditions.
The tetragonal zirconia structure gives TZP its notable resistance to crack propagation, helping improve the reliability of ceramic components under mechanical stress.
With a published bending strength of 800 MPa and compressive strength of 3,000 MPa, 3Y-TZP supports applications involving substantial mechanical loads.
A thermal conductivity below 2 W/mK and a thermal shock resistance stability value of 270°C are listed in VANCERA's technical data.
The listed volume resistance exceeds 10¹⁰ Ω·cm at 20°C. This value provides a reference when evaluating the material's electrical behavior.
A Vickers hardness of 1,150 HV 0.5 gives 3Y-TZP a hard ceramic surface for precision components exposed to contact and mechanical loading.
The compressive strength value of 3,000 MPa and elastic modulus of 205 GPa make 3Y-TZP a strong and stiff material for engineered ceramic parts.
The yttria content changes the stabilized zirconia structure and its functional characteristics. The appropriate composition depends on whether the application requires mechanical performance or high-temperature ionic conductivity.
3Y-TZP belongs to the tetragonal polycrystal zirconia family, generally described as zirconia stabilized with approximately 2–4 mol% yttria. It is selected for its excellent integrated mechanical properties and fracture toughness at room temperature.
Tetragonal Polycrystal Zirconia covers the yttria-stabilized zirconia composition range identified by VANCERA. Its main distinguishing feature is the combination of mechanical properties and fracture toughness at room temperature.
YSZ with approximately 4–8 mol% yttria is described as fully stabilized zirconia. Unlike the 3Y-TZP mechanical grade, this composition is noted for ionic electrical conductivity above 600°C and is used in selected electrochemical applications.
