Doped Zirconia Ceramic

The present invention provides the use of a doped zirconia ceramic having a mean grain size of about 190 nm or less and consisting of the tetragonal zirconia crystallographic phase as a hydrothermally stable material or in an application that requires the use of a hydrothermally stable material. The present invention also provides a doped zirconia ceramic having a mean grain size of about 190 nm or less and consisting of tetragonal zirconia which does not undergo detectable tetragonal to monoclinic transformation during aging in moisture in an autoclave at a temperature of up to about 245 DEG C for up to 504 hours at a pressure of up to 7 bar.
