Resumo
This study consisted of an investigation of the influence of powder preparation on the phase and chemical compositions and microstructure of 9.5/65/35 PLZT materials sintered in an oxygen atmosphere. The powders with the formula Pb0.905La0.095(Zr0.65Ti0.35)(0.976)O-3+3.5 wt.% PbO were prepared by the polymeric organometallic precursor method (the Pechini method and the partial oxalate procedure). Phase composition was determined by X-ray diffraction of powder and EDS analysis, while grain size was determined based on the micrograph obtained from SEM. (C) 2001 Elsevier B.V. B.V.
