Lead bismuth titanate ceramics were prepared using solid‐state method. The structural and dielectric behaviors were studied using X‐ray diffraction, scanning electron microscopy, and LCR meter. X‐ray diffraction studies showed that crystal structure changed with changing compositions and sintering temperatures. The value of dielectric constant was found to be more for lead‐free samples with the addition of 1 mol% Fe 2 O 3 rather than CrO 3 ‐doped samples. Activation energy, E a, was determined from the slope of log τ versus 1000/ T plots for ceramic samples 3P7 BT 1C800 and 3P7 BT 1C900. Impedance spectroscopy revealed that resistance decreases with increasing temperature.
