Synthesis and Characterization of Barium-Hexaferrite-Based Nanocomposite on X-Band Microwave

摘要: In this research, synthesis and characterization of barium-hexaferrite-based nanocomposites were conducted with silicone rubber as a microwave absorber in x-band frequency. Barium-hexaferrite nanoparticle powder is prepared with high energy milling for 75 h. Nanocomposites were prepared by weight percentage of barium-hexaferrite to silicon rubber with a variation of 20% to 50%. X-ray diffraction (XRD) is used for structural analysis and phase in still-powder conditions. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are used for surface morphology analysis. The vibration of sample magnetometer (VSM) and vector network analyzer are respectively used for static magnetic analysis and microwave absorption properties. The characterization results show that the sample has a single phase with a hexagonal crystal structure. The surface morphology is almost homogeneous …
