Present report is concerning with investigation of effect of different sintering profiles on Pb based BLZT ceramics. The material powder of selected composition (Ba0.795La0.005Pb0.20Ti0.90Zr0.10O3) was prepared by solid state reaction route and then powder was compacted in the form of circular discs. The discs were then sintered at different temperatures (1325 degrees C for 4h, 1325 degrees C for 15min+1200 degrees C for 4h). Improved dielectric and ferroelectric properties were observed for samples sintered at 1200 degrees C. Shifting in T-c to higher temperature could be related to enhanced tetragonality, which was further confirmed by X-ray diffraction analysis. All these improvements evidences that there is less Pb loss in case of modified sintering profile.
