• Various chemical coprecipitation techniques used for the production of PLZT (lead lanthanum zirconate titanate) 2/55/45 (La/Zr/Ti) powders were investigated. The coprecipitation condition corresponding to 0.5 M oxalic acid at a titration rate of 24 cc/min and at a temperature of 21 degrees C yielded calcined powders with the largest surface areas. This condition was thus selected as the optimum one in regard to the sinterability of the powders. The characteristics of the PLZT 2/55/45 powders under the best precipitation condition were evaluated. FTIR (Fourier-transform infrared) spectroscopy and XRD (X-ray diffraction) showed that perovskite phase formation occurred at 550 degrees C.< >
