Abstract: A method for producing magnetic particles containing a manganese-aluminum alloy includes: mixing manganese particles, an aluminum source, an activator containing a halide, and an anti-sintering agent to obtain a mixed powder; heating the mixed powder to calorize the manganese particles by utilizing gaps between particles of the anti-sintering agent formed by the anti-sintering agent, to obtain a treated mixture containing magnetic particles containing a manganese-aluminum alloy, wherein a mass ratio of aluminum to manganese (Al/Mn) in the manganese-aluminum alloy is in a range from 25/75 to 35/65; removing the anti-sintering agent from the treated mixture to recover the magnetic particles containing the manganese-aluminum alloy.

Abstract: A thermal spray particle is substantially spherical, and contains iron and aluminum. An amount of aluminum contained in the thermal spray particle is in a range of 32 wt % to 48 wt %. The thermal spray particle includes a first region, in which a concentration of aluminum is in a range of 22 wt % to 37 wt %; and a second region, in which a concentration of aluminum is in a range of 40 wt % to 50 wt %.

Abstract: A method for producing aluminum-containing particles includes mixing together treatment-target particles, an aluminum source, an activating agent, and a plurality of sintering inhibitors, thereby obtaining mixed particles, the treatment-target particles containing a heavy metal with a relative density of 4 or more and the activating agent containing a halide, heating the mixed particles to perform calorizing treatment on the treatment-target particles using gaps formed by the plurality of sintering inhibitors, thereby obtaining a treated mixture containing aluminum-impregnated particles, the gaps being between adjacent sintering inhibitors of the plurality of sintering inhibitors, and removing the plurality of sintering inhibitors from the treated mixture, thereby recovering the aluminum-impregnated particles.
