Effect of Molar Concentration of Zinc Ferrite (ZnFe2O4) Nano Particles Prepared by Sol-Gel on Microwaves Attenuation

Abstract :

NO3)3.9H2O and Zn(NO3)2.6H2O by adopting molecular concentrations (0.2 M and 0.4 M). The samples were sintered at two temperatures (800 °C , 1000°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 ?-Fe2O3 and ZnFe2O4. On The absorbance tests of the Zinc ferrite samples have been carried out for all samples by using the network analyzer device, at the X-band range (8-12) GHz. . The samples were sintered at 800°C, and 1000°C, and the concentration (0.2 and 0.4)M and the Dimensions of the samples is (23*10*10)mm. The absorbance greeter than (95) at frequency (8-12)GHz.
