“…In the ZrO 2 sample (Fig. 1e), the peaks at 30.13°, 34.88°, 50.22°, 59.87°, and 62.66° correspond to the (111), (200), (220), (311), and (222) planes of cubic-phase ZrO 2 , respectively, 40 which can be found from the PDF#(49-1642) card. Meanwhile, as displayed in Fig.…”

“…It was found also that yttria addition to Mg-PSZ using simple techniques [19] produced a material with long-term thermal stability at relatively high temperatures, a property highly demanded in sensor applications. Addition of dopants like MoO 3 to India-stabilized zirconia increased the hardness, ionic conductivity and the thermal expansion [20]. La 2 O 3 addition to ceria-based solid electrolyte enhances its ionic conductivity and thermal stability [21].…”

In this work, zirconia powders containing 5 and 10 mol % ceria were prepared by co-precipitation method followed by doping with small amounts (< 1 mol %) of gadolinia which stabilized the tetragonal phase. X-ray diffraction and scanning electron microscopy were used for phase analysis and microstructure examination, respectively. The sintered compacts showed fine grained, dense, tough and strong ceramics. Strength up to 795.8 MPa and toughness of 17 MPa√m have been obtained. These ceramics showed higher toughness than yttria-doped tetragonal zirconia polycrystals (Y-TZP) and a higher strength than the ceria tetragonal zirconia polycrystals (Ce-TZP). The high fracture toughness was attributed to the tetragonal-to-monoclinic phase transformation which was associated with ferroelastic domain switching. The domain switching toughening has been discussed in view of Chevalier's model. Four-point bending strengths for the samples tested in the as cut state are higher than those tested in the as-sintered or the ground states.
