N2 - Micro ferrite powder with magnetite phase has been successfully synthesized from iron sand using the extraction-milling method as an absorber for radar waves at the Ku-band frequency (12-18 GHz). The extraction of ferrite powder from iron sand using a strong permanent magnet. The formation of micro ferrite was carried out using a milling process with variations in time 2 h, 4 h and 6 h (hours), and milling speed 100 rpm, 150 rpm and 200 rpm. The increasing the milling speed and time causes the particle size to decrease, the average crystal size and the saturation magnetization value to decrease but the maximum Reflection Loss (RLm) value to increase in the Ku-band frequency band (12-18 GHz). Characterization of the crystalline phase, average crystal size, magnetic power, morphology of micro ferrite was carried out using XRD, VSM and SEM. The maximum Reflection Loss value is measured using the transmission line method with a VNA tool. The optimal influence of milling speed and time on radar wave absorption at a rotation speed of 150 rpm within 6 h with a saturation magnetization value of 40.60 emu g−1r−1, average crystal size of 93.95 nm, R L m = − 30.04 dB , matching frequency f m = 16 . 57 GHz and in frequency band 15.95 − 17.52 GHz . Micro ferrite made from iron sand synthesized using the high energy ball milling method has the potential to be an inexpensive alternative for making microwave absorbing materials with a simpler and environmentally friendly process.
