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 high thermal expansion and are often the material of choice for joining ceramic and steel.

Zirconium oxide, which is also known as Zirconia, is a white crystalline oxide of zirconium. Its most naturally occurring form is the mineral baddeleyite which has a monoclinic crystalline structure. Zirconium oxide products typically demonstrate excellent mechanical properties and stability at elevated temperatures.
Zirconium oxide (ZrO₂) or Zirconia, is an advanced ceramic material most commonly used in the production of different types of hard ceramics. This material is most widely used for production of various dental implants due to its hardness, chemical unreactivity and its various biocompatible aspects.
Zirconia's use in dentistry is only the most well-known use of this advanced ceramic material. There are other properties that make zirconia suitable for various applications including high thermal expansion, excellent thermal insulation, and very high resistance to crack propagation.
Very high resistance to crack propagation, making it exceptionally durable for demanding applications.
High thermal expansion similar to some types of steel, ideal for ceramic-to-metal joining.
Excellent thermal insulation with low thermal conductivity for high-temperature applications.
Superior wear resistance, stability, and scratch resistance for long-lasting performance.
Very high room-temperature strength and hardness with high density for structural integrity.
Solid electrical insulation properties combined with good frictional behavior.
