What is Zirconium Oxide?

The highest mechanical strength and fracture toughness

Zirconium Oxide (ZrO2), also known as Zirconia, boasts the highest mechanical strength and fracture toughness compared to other fine grained ceramics. Zirconium oxide exists in its monoclinic polymorph at room temperature and is used in applications such as ceramics and refractories due to its excellent thermal insulation properties.

Properties of Zirconium Oxide

The properties of Zirconium Oxide powder is dependent upon the process route used to produce the material. Chemically derived Zirconium Oxide is consistent, highly homogeneous and the textural properties can be carefully controlled. Particle size, surface area and purity can all be tailored to meet the designated application.

Zirconium Oxide is also a highly versatile material when combined with other elements. Addition of Yttrium Oxide, Magnesium Oxide, Aluminium Oxide and others can enhance the mechanical, optical or thermal properties of the ceramics produced.

What is Zirconium Oxide used for?

Zirconium Oxide (ZrO2), also known as Zirconia, can be used in a wide variety of applications across a number of markets.

Zirconium Oxide is also a highly versatile material when combined with other elements. A small addition of yttrium oxide unlocks the tetragonal polymorph and further enhances the mechanical properties and form materials suitable for advanced ceramic applications. Further addition of yttrium oxide yields the cubic polymorph and can lead to function ceramics which can conduct oxygen ions and can be used in sensors along with cubic zirconia for jewellery.
