ABSTRACT:

Strontium substituted Lead zirconate (Pb1-XSrXZrO3 ( x = 0, 0.05, 0.10, 0.15 and 0.20) ceramics have been synthesized by a novel method called urea-nitrate self-propagating combustion technique, using lead nitrates, strontium nitrates, zirconium nitrates as. oxidizer and urea?s as fuel at 550?C in preheated muffle furnace. The as-synthesized ceramic powder was heat treated at 800?C for 6h in order to get phase pure compounds. The prepared powder were characterized by XRD, FTIR, density, particle size analysis and BET surface and measurements. The XRD patterns obtained on these powders showed the formation of pure orthorhombic phase of PbZrO3 without any impurities. Thin sections of circular components of these powders were also made by uniaxial compression and were subject ed to annealing at different temperatures ranging 900?C to 1050?C for 2 h in order to throw light on their sintering behavior. The surface morphology of the sintered components was studied by SEM.
