Zirconium Oxide ZrO2 (also known as zirconia) is a material with very high resistance to crack propagation.  Another outstanding property combination is the very low thermal conductivity and high strength.

Used in applications such as precision bearings, pumps and valves, check valves, flow meters, and measurement instruments that operate in aggressive environments. They are used in the medical field as this is a very pure material as well as in grinding and milling functions.
