摘要： A high-frequency magnetic material (3) includes: metal particles (1) of one of Fe and Co or alloy particles based on at least one of Fe and Co; and an oxide phase (2) containing a matrix phase and a metal oxide having a larger valence than the matrix phase. The matrix phase contains a non-reducible metal oxide and the metal oxide having a larger valence than the matrix phase forms a solid solution with the matrix phase.

摘要： A ceramic composite material includes: a silicon nitride grain; and a silicon carbide grain, the silicon nitride grain includes 80% or more β-type silicon nitride, and in a cross section of the ceramic composite material, an average grain size of the silicon nitride grains is not less than 0.1 µm nor more than 10 µm. In the cross section, the silicon nitride grain having a grain size three times or more as large as the average grain size has an area proportion of 35% or less to all the silicon nitride grains.

摘要： A radiowave absorber of an embodiment includes: core-shell particles (1)each including: a core portion (10) that contains at least one magnetic metal element selected from a first group including Fe, Co, and Ni, and at least one metal element selected from a second group including Mg, Al, Si, Ca, Zr, Ti, Hf, Zn, Mn, rare-earth elements, Ba, and Sr; and a shell layer (20) that coats at least part of the core portion, and includes an oxide layer (21) containing at least one metal element selected from the second group and contained in the core portion; and a binding layer (30) that binds the core-shell particles, and has a higher resistance than the resistance of the core-shell particles. The volume filling rate of the core-shell particles in the radiowave absorber is not lower than 10% and not higher than 55%.
