Strontium hexaferrite bulk samples ( SrFe 12 O 19 ) were prepared via ceramic method with the dimensions of { diameter ( D = 3 cm ) and thickness ( t = 2.5 mm )}, and investigated using the vector network analyzer within X-Band waves (frequency bandwidth ( 8-12 ) GHz). Three samples have been sintered from this type of ferrite with three temperatures ( 1000, 1050, 1100 ) °C. The samples which were sintered with 1050°C and 1100°C having best absorption from the other samples, because the ferrite is not completely formed in this temperature and the ferrite was passed with different phases led to the absorption of the microwave. The results of X-ray diffraction ( XRD ) showed compatibility with standard results except for some secondary phases with the ferrite samples.
