Abstract
In this work, Lead zirconate titanate ceramics (Pb(Zr_<0.52>Ti_<0.48>)O_3: PZT) were prepared by conventional mixed oxide method. The optimum temperature for calcinations the formation of phase pure perovskite was found to be about 750℃ for 2 h with heating rate of 10℃/min. Phase formation was examined by X-ray diffraction (XRD). The sintering procedures were carried out at 1150 and 1200℃ for 6 h with heating rate of 3, 5 and 10℃/min. Influence of heating rate on physical properties and microstructure were investigated. The results show that at percent of linear shrinkage and densification were decreased with increased heating rate. However, the average grain size of PZT ceramics was not much influence by heating rate.
