Structural, dielectric and impedance properties of the synthesized composites were investigated and discussed in detail. The X-ray diffraction technique shows that all the samples possessed a double-phase polycrystalline sample with a tetragonal-rhombohedral structure. Dielectric and impedance behavior were investigated in a wide range of temperatures (room temperature (RT) - 500˚C) and frequency (100 Hz ≤f ≤ 1 MHz). A broad dielectric constant peak was observed around the phase transition temperature.</p> ER -
