Description

Zirconium dioxide has the unique feature that it impedes the spread of cracks through the so-called transformation toughening mechanism. No other ceramic material shows such a high fracture toughness combined at the same time with such high stability. It has following features:


  • Thermal insulation
  • Thermal resistance
  • Flexural Strength
  • Electrical insulation
  • Fracture toughness
  • Los datos sobre este material han sido proporcionados por Bosch Advanced Ceramics.

    A menos que se indique lo contrario, todas las medidas corresponden a condiciones de temperatura ambiente. A menos que se indique lo contrario, se utilizan las unidades del SI.
    Las normas armonizadas son similares a uno o varios estándares del proveedor. Es posible que algunas normas armonizadas se ajusten al estándar original, mientras que otras pueden quedar fuera de su alcance.
