Zirconia

Zirconia is applied as partially stabilized zirconia (PSZ) or tetragonal zirconia polycrystals (TZP). Both materials exhibit very good mechanical strength, fracture toughness and thermal shock resistance. The coefficient of thermal expansion of these materials is comparable with steel. Zirconia is often used in wear applications requiring improved fracture toughness and stiffness over alumina.

PSZ exhibits very high mechanical strength, fracture toughness and wear resistance. Due to these properties the parts made of PSZ zirconia are used in all technical sectors.

TZP zirconia shows the highest mechanical strength, fracture toughness and wear resistance. Parts made from this material satisfy the highest requirements concerning mechanical properties, surface roughness and edge stability. The specific properties of TZP materials enable the production of highest quality blades with superior quality.
