Ba 0.7 Sr 0.3 Zr x Ti 1− x O 3 ( BSZT ; where x =0.02, 0.04, 0.06, 0.08, 0.1) ceramics were processed through a sol‐gel method at 1450°C for 6 h. All the samples showed a diffuse phase transition which might be due to the presence of polar nanoregions, those associated with the composition inhomogeneity in the BSZT ceramics. The sample with x =0.02 exhibited a dielectric constant (ɛ=23714) which successively decreased with increasing x up to 8569 for the sample with x =0.1 around T c measured at 10 kH z. Ceramic samples showed a ferroelectric hysteresis behavior similar to relaxor materials.
