| Abstract Scope |
Yttria-stabilized zirconia (Y-TZP) is used as a biomaterial in dentistry due to its mechanical properties and biocompatibility. In this study, 5Y-TZP (5% Y) was sintered at different heating rates up to 1500 ºC after being subjected to various compaction pressures. Relative density measurements were performed using the Archimedes method, and wettability measurements, Vickers microhardness tests, and toughness measurements were conducted. The results showed that samples subjected to a slower heating rate during sintering exhibited more homogeneous microstructures, higher mechanical strength, and toughness. The low heating rate improved the wettability. It is concluded that the compaction pressure and heating rate are crucial for optimizing the mechanical and functional properties of 5Y-PSZ zirconia, thereby making it even more effective under clinical conditions. |
