Effects of niobium doping on dielectric and ferroelectric properties of chromium modified lead zirconate titanate ceramics

Effects of niobium doping on dielectric and ferroelectric properties of unmodified lead zirconate titanate (PZT) and chromium modified lead zirconate titanate (Cr-modified PZT) have been investigated. The x-ray structural study shows the phase formed depending on the dopant concentrations with incre...

The x-ray structural study shows the phase formed depending on the dopant concentrations with increasing the doping content tending to an increase in the rhombohedral phase in both of PZT and Cr-modified PZT ceramics.

However, coercive field decreases, and the remanent polarization tends to increase with increasing niobium concentration from 1-3 mol% in Cr-modified PZT ceramics. Further increase in niobium concentration results in a drop of the remanent polarization and the coercive field.
