Özet
In this work, composite materials of BaTiO3/CoFe1.98Nb0.02O4 with desirable physical properties were developed. Magnetic CoFe1.98Nb0.02O4 and dielectric BaTiO3 phases were initially prepared via hydrothermal and sol-gel methods, respectively. Next, diverse materials of (100-x)% BaTiO3 + x% CoFe1.98Nb0.02O4 (x = 0, 2, 5, 10, 20, and 100 %) were developed using a solid-state reaction. The development of biphasic materials is confirmed through X-ray diffraction (XRD) and energy dispersive X-rays (EDX) analyses. Scanning electron microscope (SEM) observations indicated the existence of dissimilar particles in terms of shape and size, which belong to CoFe1.98Nb0.02O4 and BaTiO3 phases. The variations of dielectric constant and loss tangent were also investigated at ambient temperature in a frequency range of 100 to 106 Hz. Low values of dielectric loss tangent lesser than 1 are observed for different composites (i.e., x = 2, 5, 10, and 20 %). More specifically, composite materials with x >= 5% displayed very low dielectric loss tangent (below 0.1) along with good stability over the whole range of frequency. The obtained results indicated that these composite products could be suitable for high-frequency electromagnetic device applications.
