In this work, the result of calcination temperature on phase formation and microstructure of (Pb_<1-x>Ba_x)TiO_3 ; 0.025≤x≤0.010 (PBT) powders were investigated. The PBT powders were prepared via the mixed oxide method under various calcinations temperatures (400-900℃). The TGA-DTA and XRD were evaluated the optimum conditions for calcinations. The c/a ratio increased with increasing calcination temperature up to 800℃ and the high purity of perovskite powders were obtained with calcination temperature at 800℃. The SEM result indicated that the particle size of the powders increased with increasing calcinations temperature.
