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.

对于氧化锆（Y-TZP），即使在1350 ℃的烧结温度下增加压热处理时间，也没有观察到向单斜相的转变。在1450 ℃以上，随着处理时间的延长，单斜相含量增加。此外，对于在1450 ℃以上烧结的Y-TZP，观察到压热处理后的维氏硬度降低的趋势。烧结温度的影响在Y-TZP中比在本研究的结果中大得多，并且当烧结温度变高时，很明显，它变得容易通过压热产生低温降解。
