Dielectric and ferroelectric properties of (Cr,Nb)-doped lead zirconate titanate ceramics

The 3 mol% Nb2O5 doped Pb(Zr0.52Ti 0.48)O3 with addition of 1-3 mol% Cr2O3 prepared via the solid-state reaction technique have been investigated. The XRD shows that a sample is primarily in both tetragonal and rhombohedral phases coexist and the amount of rhombohedral phase decreases that is due to...
