    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.
