Zirconium Oxide

What is it?

Zirconium oxide (or cubic zirconia) is a polymorphous crystalline substance chemically extracted from zirconium silicate and baddeleyite.


Thanks to its crystalline structure, it displays excellent mechanical resistance to stress and the following useful characteristics, making it valuable for a number of applications. This is the most elastic and robust technical ceramic, and therefore the least fragile: the elasticity and heat expansion coefficients are similar to those of steel.


Zirconium oxide offers exceptional properties. It is therefore an important material in a wide range of mechanical, electronic, nuclear and design applications. Moreover, zirconium oxide has no systematic toxicity, making it ideal for use in dentistry.

Zirconium oxide properties:

  • Excellent hardness
  • Chemical and heat resistance
  • Good resistance to temperature changes
  • Low heat conductivity
  • Low heat expansion
  • High resistance to wear
  • Low attrition rate
  • Resistance to fracturing
  • High resistance to chemical aggression
  • Excellent aesthetic qualities not achievable by metals

Products made using zirconium oxide:

  • Plastic processing applications
  • Cutting tools
  • Tubing and conduits
  • Spheres
  • Extrusion tools
  • High-performance ceramic tubes
  • Sealing technologies
  • Automotive bearings
  • Dental implants
  • Jewellery
  • Accessories
