摘要
A new hexaferrite composition, BaCoxSix+yFe12-2x-yO19 (x = 0.90; y = 0.05), in fine (similar to mu size) powder form, is prepared. Ferrite paint formulations are made by dispersing this powder in different weight proportions in an epoxy resin. X-band (8-12 GHz) microwave absorption behaviour of the paint coatings of different thicknesses is studied. Remarkably high value, greater than or equal to 10 dB, of signal absorption at 9.5 GHz is observed for a coating thickness of 0.60 mm with a ferrite fill factor of 57 wt%.
