Zirconia (ZrO2) is a unique advanced ceramic. Products manufactured from zirconia powder exhibit superior mechanical properties such as high strength and flexibility. Heat insulating properties and oxygen-ion conductivity indicate zirconia has potential for use in a wide variety of applications - everything from telecommunications to the new energy of the future and environmentally beneficial products.

Zirconia offers chemical and corrosion resistance to temperatures well above the melting point of Alumina. In its pure form crystal structure changes limit mechanical applications, however stabilized Zirconias produced by addition of Calcium, Magnesium or Ytrium Oxides can produce very high strength, hardness and particularly toughness. In addition the material has low thermal conductivity and is an ionic conductor above 600°C. This has lead to applications in oxygen sensors and high temperature fuel cells.
