Preparation of Nano Crystalline Zinc –Ferrite as Material for Micro Waves Absorption by Sol-Gel Methods


  • Department of Physics, College of Science, University of Wasit, Alrabie, Wasit, Iraq


Objective: To prepare zinc ferrites materials and study the sintering effect on the structural and microwaves absorption in the X-band rang. Methods/Statistical Analysis: Zinc Ferrite nanoparticles have been prepared by using the sol-gel methods. The samples were sintered at three temperatures (400°C, 600 °C, 800 °C) for two hours. The spinal phase of zinc ferrite structure and crystallite size was examined by XRD spectrum, pattern show that nanoparticles structure exhibit mixed phase of ZnO and ZnFe2O4.Atomic force microscopy (AFM) was used to study the surface topography. AFM images reveal a uniform distribution of semispherical shaped nanostructure with average grain sizes ranging between (70.71 nm -92.03 nm). The microwave absorption in X-band rang was examined with a vector network analyzer (VNA). Findings/ Application: The maximum microwave absorbance at 9 GHz for sample sintering at 800 °C with narrow bandwidth (8.5- 9.5 GHz). The minimum the attenuation coefficient is less than -15 dB with absorber thickness (1.2 cm) for all samples.
