YTZP
YTZP stands for yttria-stabilized tetragonal zirconia polycrystal, a ceramic material in which zirconia (ZrO2) is stabilized with yttria (Y2O3). The yttria dopant maintains a metastable tetragonal phase at room temperature, enabling a stress-induced tetragonal-to-monoclinic transformation that produces transformation toughening and enhances fracture resistance.
The material is known for a combination of high strength, high fracture toughness, and good wear resistance,
Manufacturing and processing typically involve powder synthesis, stabilization, and sintering to achieve full density. In dentistry,
Applications are concentrated in dentistry, where Y-TZP is used for monolithic crowns and fixed dental prostheses,
Limitations and aging are considerations: Y-TZP can undergo low-temperature degradation in moist environments, leading to surface
