  • Partially stabilized zirconia biocomponent having high resistance to low temperature degradation and a method of preparing same
    Publication number: 20020031675
    Abstract: A biomedical component comprising sintered yttria tetragonal zirconia ceramic (YTZP), the YTZP comprising at least 90 mol % ZrO2, the ZrO2 being partially stabilized with at least 2.1 mol % yttria, wherein the YTZP further comprises between 0.05 wt % and 1 wt % alumina, wherein the YTZP has a density of at least 99% of theoretical density and has a grain size, as measured by the linear intercept method, of no more than 1 micron, and wherein the yttria is homogeneously distributed within the zirconia.
