Manganese Substitution Effect on the Perovskite-type Pb(Zr0.53Ti0.47)O3 Structure

Bulk materials of Mn doped Pb(Zr0.53Ti0.47)O3 of composition close
to the morphotropic phase boundary have been prepared by solid state route.
The influence of various Mn contents, 0.004 , 0.008 and 0.016, on the
perovskite type structure of the materials are examined using XRD technique.
The types of Mn-ions substitution in the original structure are considered with
respect to deviation from the ideal tolerance value (t = 1). The results
confirmed the presence of two coexisting perovskite unit cells, tetragonal and
rhombohedral, throughout the various compositions used and the
rhombohedral phase becomes dominant at higher Mn contents. An attempt is
also made using Rietveld to establish the exact location of the various ions
displacements in the tetragonal unit cells.
