  • Publication number: 20100045505
    Abstract: A radio wave absorption material is characterized to be obtained by firing a ferrite material that is formed by adding an accessory component, 0.1 to 2 wt % of CoO, to an oxide magnetic material containing main components, 30 to 49.5 mol % of Fe2O3, 0.5 to 20 mol % of Mn2O3, 5 to 35 mol % of ZnO, 0.2 to 15 mol % of (Li0.5Fe0.5)O and MnO as the rest. In the above-mentioned composition, part of ZnO may be replaced with 20 mol % or less of CuO. This radio wave absorption material has high strength and humidity stability and has excellent radio wave absorption performance although low in cost.
