Insight into the Hardness of Zirconia Ceramics

Technical zirconia ceramics are subsequently partially-stabilised with a regent like yttria (Y 2 O 3), which helps to maintain the outstanding mechanical qualities up to maximum operating temperatures of approximately 1000°C (1832°F). Hardness is one of the key properties that makes yttria-stabilised zirconia ceramics so desirable.

Zirconium dioxide - Wikipedia

Zirconium dioxide (ZrO 2), sometimes known as zirconia (not to be confused with zircon), is a white crystalline oxide of zirconium.Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite.A dopant stabilized cubic structured zirconia, cubic zirconia, is synthesized in various colours for use as a gemstone and a diamond simulant.
