The effect of B-site substitution of Ce4+on the microstructure of the Pb[Zr0.9(CexTi1-x)0.1]O3(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 Ce4+substitution causes the in-phase tilting of the oxygen octahedra and results in the 1/2{hk0} superlattice reflections. With 7mol% addition of Ce4+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.
