Strontium substituted barium zirconate Ba1-xSrxZrO3 (x = 0, 0.05, 0.10, 0.15 and 0.20) ceramics have been prepared by a urea-nitrate combustion technique, using barium nitrate, strontium nitrate and zirconium nitrate as oxidizers and urea as fuel at 5000C in a pre-heated muffle furnace. The as- synthesized powders were heat treated at 8000 C for 6 h in order to get phase pure compounds. The heat treat powders were characterized by XRD, density, BET surface area and particle size measurements. The XRD pattern obtained on these powders showed the formation of cubic phase of BaZrO3. Thin section of circular component of these powders was also made by uniaxial compression and were subjected to annealing at different temperatures from 900 to 10500 C for 2 h. The surface morphology of the sintered components was studied by scanning electron microscopy.
