dc.description.abstractZrTiO4 (ZT), obtained by the Pechini method, was used as precursor for obtaining PLZT (lead lanthanum zirconium titanate). An aqueous solution of oxalic acid was prepared with particles of ZT, Pb(NO3)(2) and La2O3. After the PbC2O4 and La2O3 precipitate on ZT particles, the materials were calcined and X-ray diffraction (XRD) showed the cubic phase of PLZT. This material was sintered, in two steps, and a density of about 8.0 g/cm(3) was obtained. After the second sintering the XRD pattern showed the occurrence of tetragonal and rhombohedral phases. This was caused by a stoichiometric deviation and the material showed a high optical transparency. (C) 1998 Elsevier B.V. B.V. All rights reserved.
