In this study, ceramics within the (1x)Pb(Zr1=2-Ti1=2)O3–(x)Pb(Co1=3Nb2=3)O3 solid solution system (where
x¼0:1{0:5) were successfully prepared using a solid-state
mixed-oxide technique. The PZT ceramic was identified
by XRD analysis as a single-phase tetragonal perovskite,
while the addition of PCN resulted in a gradual shift from
tetragonal symmetry to pseudo cubic symmetry, with a
possible MPB between the two phases located near the
0.7PZT–0.3PCN composition. However, the dielectric and
ferroelectric properties did not show anomalously high value
for the dielectric and ferroelectric properties at the 0.7PZT–
0.3PCN composition, indicating that the MPB composition
shifted to0:2x0:3in the PZT–PCN system
