Zirconium Oxide Ceramic

Zirconia Ceramic Parts

1.Very high resistance to crack propagation

2.High thermal expansion

3.Excellent thermal insulation/low thermal conductivity

4.Very high resistance to crack propagation, high fracture toughness

5.Ability to conduct oxygen ions (used for the measurement of oxygen partial pressures in lambda probes)

Detail Description:

Zirconium oxide (ZrO2 –also known as zirconia) is a material with very high resistance to crack propagation. Zirconium oxide ceramics also have very high thermal expansion and are therefore often the material of choice for joining ceramic and steel.

Another outstanding property combination is the very low thermal conductivity and high strength. In addition, some types of zirconium oxide ceramics can conduct oxygen ions. Components made from this material are significantly more expensive than components made of alumina ceramics.
