increase in PCN content, confirming the diffuse phase
transitions in PZT–PCN solid solutions. It is clear that the
addition of PCN increases the degree of disorder in
(1x)PZT–(x)PCN over the compositional range0:1x
0:5with the highest degree of diffuseness exhibited in the
0.5PZT–0.5PCN composition. It should also be mentioned
here that different dielectric behaviors could also be caused
by grain size variation,
