Tailored Synergy: Synthesis and In-Depth Structural Analysis of x[Ni0.2Cu0.3Co0.5Fe2O4] + (1-x)[Ba0.7Sr0.3TiO3] Composites

M E Composites with composition x[Ni0.2 Cu0.3 CO0.5 Fe2 O4 ] + (1-x)[Ba0.7Sr0.3TiO3 ], Where x varying from 0.1 to 0.4 in molar ratio, were prepared by standard double sintering ceramic technique. The presence of ferrites phase, namely [Ni0.2 Cu0.3 CO0.5 Fe2 O4 ] and ferroelectric phase, namely [Ba0.7Sr0.3TiO3 ], were confirmed by X-Ray Diffraction analysis, whereas SEM micrographs were obtained to study the morphology of samples. The x ray diffraction patterns exhibit a set of well-defined ferrites and ferroelectric peaks. The tetragonality ratio c/a, of the ferroelectric phase remains the same in all the samples, the porosity varies from 20% to30% while the average grain diameter lies in the range of 0.5µm to 2 µm.
