Abstract
A method of producing a nanocomposite thermoelectric conversion material includes preparing a solution that contains salts of a plurality of first elements constituting a thermoelectric conversion material, and a salt of a second element that has a redox potential lower than redox potentials of the first elements; precipitating the first elements, thereby producing a matrix-precursor that is a precursor of a matrix made of the thermoelectric conversion material, by adding a reducing agent to the solution; precipitating the second element in the matrix-precursor, thereby producing slurry containing the first elements and the second element, by further adding the reducing agent to the solution; and alloying the plurality of the first elements, thereby producing the matrix () made of the thermoelectric conversion material, and producing nano-sized phonon-scattering particles () including the second element, which are dispersed in the matrix (), by filtering and washing the slurry, and then, heat-treating the slurry.
