| titleOfInvention | Powder for electromagnetic wave absorber |
| abstract | A powder for an electromagnetic wave absorber having excellent electromagnetic wave absorption characteristics is provided. In an electromagnetic wave absorber containing a soft magnetic metal powder for a band of 1 to 10 GHz, the average particle diameter of the powder used in spherical conversion satisfies the following formula (1), and this is flattened to an aspect ratio of 10 or more. Processed powder for electromagnetic wave absorber. −0.45d + 6 ≦ fp ≦ −0.45d + 12 (1) where d: average particle diameter, fp: frequency used, and in addition to the above, water atomized gas or gas atomized powder of 150 μm or less. A powder for an electromagnetic wave absorber obtained by flattening a metal powder having a Vickers hardness Hv of 200 or less and an elongation value satisfying the following formula (2). 0.14E + 5 ≦ d ≦ 0.14E + 9 Formula (2) where E: elongation, d: average particle size [selection diagram] None |
