ZIRCONIUM OXIDE / ZRO2 3Y-TZP - MG-PSZ

Zirconium oxide is the high-performance material among oxide ceramics. It is characterized by exceptional fracture toughness, high wear and corrosion resistance, and low thermal conductivity.

THE ADVANTAGES OF ZIRCONIA CERAMICS

 

  • Very high fracture toughness

  • Very high flexural and tensile strength

  • High wear resistance

  • High compressive strength

  • Very low thermal conductivity

  • Thermal expansion similar to cast iron

  • E-module comparable to steel

  • Oxygen ion conductivity

  • Very good tribological properties

  • Excellent surface quality and sharp edges possible

MIXED OXIDS / ATZ - ZTA

The optimal properties of both materials are realized in our mixed oxide ceramics.

-Main component ZrO2 are called ATZ (Alumina Toughened Zirconia)

-Main component Al2O3 are called ZTA (Zirconia Toughened Alumina)

THE ADVANTAGES OF MIXED OXIDE CERAMICS

 

The background of the mixtures is to combine the "good" properties of both oxides:

The great strength and toughness of zirconium oxide with the hardness and wear resistance of aluminum oxide.

With a suitable proportion of ZrO2 in the ZTA material, the high electrical insulation of the Al2O3 is retained.
