Abstrakt: Yttrium stabilized tetragonal zirconia polycrystalline (Y-TZP) ceramics containing 2 mol% and 2.5 mol% yttria were prepared by mixing 3 mol% yttria-doped zirconia powders with yttria-free zirconia powders. The microstructures of the sintered samples were studied using SEM, XRD, and Raman spectra. In addition, an ultra-sharp V-notch (??
