Description

With this kind of mixed ceramic, a small amount of aluminum oxide is added to the zirconium oxide to significantly improve the wear-resistance, elasticity and toughness. It has following features:


  • Thermal insulation
  • Flexural Strenth
  • Electrical insulation
  • Temperature and thermo shock resistance
  • Fracture toughness
  • This material data has been provided by Bosch Advanced Ceramics.

    All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
    Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
