Abstract
It is well know that the mechanical properties of the yttria stabilized zirconia (Y-TZP) is degaaded by hydrothermal treatment. In this study, effect of various acidic solvents on disintegration of Y-TZP under hydrothermal condition was investigated. The Y-TZP sintered body was disintegrated into much finer particles, since hydrochloric or nitric acid effectively proceeded the pahse transformation by extraction of yttrium.
