Notes:
Zirconia-toughened alumina (ZTA) ceramics with Ce-TZP (tetragonal zirconiapolycrystalline doped with ceria) volume fraction on 33% were prepared with the addition.. Theinfluence of glass infiltrated method was investigated. Coprecipitated Zr and Ce hydroxide mixturewas obtained from ZrOCl2.8H2O and CeCl3. 7H2O aqueous solution. CeO2-ZrO2 calcinated powderwas compacted and the compacted samples were sintered at 1180ºC. Powder samples werecharacterized by scanning electronic microscopy (SEM), The volume fraction of each phase, thegrains size and shapes, and the porosity were investigated with SEM. The relative density andshrinkage was investigate too. The results showed that the crystalline matrix was composed bySiO2 -B2O3-La2O3-Al2O3-Ce-TZP and revealed the important role played the glassy phase in thedensification of this ceramic composite
