ZrO2 Zirconia Ceramic Insulator Ring

Unlike other ceramic materials, 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.

Zirconia is characterized through its tribological performance (friction and wear) in moving applications and furthermore:

- Excellent fracture toughness

- Very good wear resistance

- High corrosion stability

- Low thermal conductivity

- CTE in range of steel
