Abstract

Abstract: The W-type Barium hexaferrite particle have been successfully synthesized by mechanical milling route. The formation of phase BaFe16 Co2 O27 through two-stage mechanism which starts with the formation of BaFe19 O19 . The synthetic result is tested by X-ray Diffraction (Cu(Kα) to determine a structure and formation phase. The magnetic characteristic is tested by permeagraph in saturating field up to 1.5 Tesla. The synthetic result shows that the partial substitution of Fe 2+ ions with Co 2+ ions influence the change in magnetic properties particularly coercivity. W-hexaferrite has a promising potential in microwave absorption application in the future especially in the range at 8 Ghz to 9, 0 GHz.
