| Research Abstract |
For zirconia (Y-TZP), even if the time of autoclave processing of sintering temperature at 1350 ℃ increased, the transformation to monoclinic was not observed. Above 1450 ℃, the increase in monoclinic content was observed with the increase in processing time. Moreover, as for Y-TZP sintered above 1450 ℃, the tendency for the Vickers hardness after autoclaving to decrease was observed. The influence of sintering temperature was very greater in Y-TZP than in the result of this research, and when sintering temperature became high, it became clear that it became easy to produce low-temperature degradation by autoclaving.
