This paper reports that lead zirconate titanate (PZT) with several Zr/Ti ratios was prepared by the organic solution of citrates of the respective cations. The Rietveld method was applied to perform quantitative analysis of the coexisting phases. The ratio of tetragonal/rhombohedral phases increased with calcination temperature. For the composition where Zr/Ti = 53/47, the tetragonal quantity varied from 25% to 35% for temperatures ranging from 600[degrees] to 800[degrees]C. For the powder with Zr/Ti = 57/43, only the rhombohedral phase was observed after calcination at 700[degrees]C. For the powder with Zr/Ti = 49/51, only the tetragonal phase was observed after calcination at 800[degrees]C. The amount of tetragonal phase was controlled in Zr/Ti = 55/45 by seeding the powder with the tetragonal phase of PZT.
