Preparation of Pb(Zr,Ti)03 Through the Use of Cupferron

An organic chelation reagent, cupferron, was used to coprecipitate Ti4+ andZr4+. After the materials were fired, they were mixed with PbO powder and fired again at high temperatures to obtain Pb(Zr,Ti)03 (PZT). It was confirmed that this method is useful for the preparation of homogeneous PZT having no compositional fluctuations. No coexistence range of the tetragonal and rhombohedral phases was observed in the PZT compositions near the morphotropic phase boundary.
