Abstract
The effect of B-site substitution of Ce 4+ on the microstructure of the Pb[Zr 0.9(Ce x Ti 1− x ) 0.1]O 3 (0≤ x≤0.7) ceramics is studied by transmission electron microscopy (TEM). For x=0, only 1 2 {hkl} superlattice reflections are found in the selected area diffraction patterns (SADPs), which correspond to the anti-phase rotation of the oxygen octahedra. Small amount of Ce 4+ substitution causes the in-phase tilting of the oxygen octahedra and results in the 1 2 {hk0} superlattice reflections. With 7 mol% addition of Ce 4+ on the B-site, the superlattice reflections at the 1 4 {hk0} pseudocubic positions can be observed, indicative of the existence of the antiferroelectric (AFE) phase. The result conforms to the polarization–electric field ( P– E) hysteresis loop measurements on the corresponding bulk ceramic samples.
