The preparation conditions for barium titanate zirconate [Ba(Ti0.70Zr0.30)O3] ceramics by the combustion method were studied. The X-ray diffraction pattern indicated that the calcined powders belonged to a cubic phase. The maximum percentage of the cubic perovskite phase was found in the sample calcined at 850 degrees C. A pure cubic crystal structure was found in all ceramic samples. The average grain size increased with increasing sintering temperatures. The dielectric constant-temperature plots showed a maximum peak value of 5800 from ceramic sintered at 1350 degrees C. The densities of samples corresponded to the dielectric constant. A diffuse phase transition was also observed.
