Zirconium oxide is used to make heat resistant crucibles, ceramics and abrasives. A red-hot crucible made from it can be plunged into cold water without cracking. Zirconium oxide is to be found in ultra-strong ceramics that are stronger and sharper even than toughened steel and are used for knives, scissors and golf irons.

Interestingly, however, yttrium-stabilized zirconium oxide Y-TZP is often not resistant in a humid atmosphere, e.g. in water vapor. This is referred to as hydrothermal degradation . The degradation process increases from about 150 °C onwards. Presumably, the water vapor dissolves the somewhat larger yttrium ions out of the crystal.
