Popis: The influence of hydrothermal action on the physical and mechanical properties of ZrO2–Y2O3(3 mol%) ceramics was investigated. The properties of specimens sintered at 1350°C in air and at 1850°C in vacuum followed by oxidative annealing at 1200°C in air were compared. The characteristics of specimens sintered at 1850°C were shown to be practically unchanged after hydrothermal treatment while specimens sintered at 1350°C showed a significant drop in strength and hardness of about 40 – 50%.
