Due to the coactivity of ferrites, it has good magnetic properties and this places it as a major player in the fabrication of microwave components. This research was undertaken to further understand best composition of ferrites composites good for microwave absorption and fabrication of the electronics. Investigation on the structural and morphological properties of the synthesized Ni1−xZnxFe2O4 composites was carried for different nominal composition for x=0.1, 0.3, 0.5 0.7 and 0.9. Fourier Transform Infra-red Spectroscopy (FTIR) was carried out to understand both the absorption and transmittance characteristics of the composites while Scanning Electron Microscope (SEM) was used to study the surface morphology of the composites. The results from characterization showed that the composition of (Ni0.9Zn0.1Fe2O4) had the highest transmittance. The surface morphology (x=0.9) showed that particles were uniformly distributed in the composites which was attributed to good preparing technique. However, there was evidence of irregular particles shape homogenously scattered in the composites with sizes ranging from 200 to 536 μm. Based on the results obtained, it is concluded that the Ni0.9Zn0.1Fe2O4 composites is better for microwave radiation absorption and the composites can be used for the fabrication of electronic and telecommunication devices.
