【 摘 要 】

In this study, Zn-doped Barium M-Heksaferrite (BaFe11.7,Zn0.3O19) powders have been prepared by coprecipitation processing from iron sand, BaCO3, and Zn powders, followed by calcined l000°C for 5h. The powders were characterized by X-ray Diffractometry (XRD), Vibrating Sample Magnetometer (VSM), conductivity measurement and Vector Network Analyzer (VNA). The XRD patterns indicated that 2 phases, there were Barium M-Hexaferrite phase (dominant phase) and Hematite phase, with conductivity value on 6x10-6 S/cm and be include as semiconductor material. The hysterisis curve showed that was a soft magnetic with coercivity field (Hc) on 0.0506 kOe. The powders was mixed on paint 10% of total weight and coated on steel grade AH36. The maximum of reflection loss on x-band frequency was -29.1 dB on frequency of 9.34 GHz and have almost 87.70% electromagnetic energy absorbed by Zn-doped Barium M-Heksaferrite (BaFe11.7Zn0.3O19).
