PURPOSE: An electromagnetic wave absorber, method for manufacturing the same and appliance using the same is provided to obtain superior electromagnetic wave absorbing characteristics, while reducing manufacturing procedures. CONSTITUTION: An electromagnetic wave absorber comprises composite magnetic particles having a grain size smaller than 10 micron meter, and the magnetic metal grains and ceramic are formed integrally into a single unit. A method for manufacturing an electromagnetic wave absorber, is characterized in that composite magnetic particles including magnetic metal grains and ceramic formed integrally into a single unit, are formed through a mechanical alloying method for a magnetic metal powder and a ceramic powder. |
