Abstract: The microstructure-property relationship of calcium doped PbZr 0.94Ti0.06O3 (PZT 94/6) ceramics has been studied. It was found that calcium doping on the A-site turns the ferroelectric PZT 94/6 into antiferroelectric. 1/2 {hk0} superlattice reflections were observed in the selected area diffraction pattern (SADP) of PZT 94/6 which indicated an in-phase oxygen octahedra tilting in the ferroelectric PZT 94/6. When 4 mol% of calcium was added as a dopant, the material became antiferroelectric at room temperature, with the characteristic 1/4 {hk0} superlattice reflections observed in the SADP. The P-E hysteresis loop measurement also supports this conclusion. As the temperature increased, an AFE-FE phase transition occurred and this was accompanied by a hunch-like dielectric anomaly at around 140°C. © Springer Science + Business Media, LLC 2006.
