| Abstract: | Mullite/Y-TZP(Yttria-doped Tetragonal Zirconia Polycrystal) composites, made from ultrafine powder prepared by chemical coprecipitation, were sintered in air. The fracture strength of Y-TZP composites at room temperature and 1000, affected by different percent of mullite,were studied. At the same time, the mechanism of rod-like mullite grains dispersing and reinforcing Y-TZP composites was discussed in the paper. |
