Preparation and Characterization of SrFe12O19/ZrO2Nanocomposite by using Sol-Gel method.

Strontium hexaferrite and Zirconium oxide (SrFe12O19 - ZrO2) nanocomposite were prepared by sol-gel method in different weight percentage. In this method Strontium nitrate, iron nitrate and zirconium oxy chloride were used as a raw materials and glucose acted as a fuel. Fourier transforms infrared spectroscopy (FTIR). The wave number 453-511cm-1 indicated the presence of the ferrites. Thermogravimetry analysis (TGA/DTA) curve above 8500C confirming the formation of the stable Strontium hexaferrite. The SrFe12O19 - ZrO2phase structure, functional groups were analyzed by X-ray diffraction (XRD) the formation of pure crystallized nanocomposite occurred when the precursors were calcined at 800°C for 3 hours. The morphology and quantitative analysis of the prepared particles were studied by using SEM and EDX spectrum. M-type strontium hexaferrite magnetic resonance frequency range is 11.51 GHz. Strontium hexaferriteconfirms that the material can be considered for high frequency applications.
