Abstract

Amorphous Fe-B particles were prepared by a direct reduction method. Resin composites were then prepared by mixing the amorphous Fe-B particles with several types of resins. The resin composites showed a relative permeability of μ r=6.4-8.5 at 1 GHz, and exhibited good microwave absorption properties in the quasi-microwave band (1-3 GHz). In particular, the composites prepared with polyvinyl pyrrolidone or acrylic-type silicone resin had good microwave absorption properties with matching thicknesses of d m = 2.0-3.7 mm and d m = 2.0-3.9 mm, respectively.
