<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a nano-composite thermoelectric conversion material in which phonon scattering particles are further micronized to raise interface density, resulting in improved thermoelectric conversion characteristic, and to provide the nano-composite thermoelectric conversion material manufactured by the method. <P>SOLUTION: The method of manufacturing the nano-composite thermoelectric conversion material in which phonon scattering particles of nano size are dispersed in the matrix of thermoelectric conversion material with nano-size interval includes the steps of: synthesizing nanoparticles that are constituent elements of thermoelectric conversion material; forming nanoparticles of thermoelectric conversion material by forming an alloy by subjecting the nanoparticles of constituent elements to hydrothermal treatment in oxidative atmosphere, and at the same time, forming a thin oxide layer on the surface thereof; and subjecting nanoparticles of the thermoelectric conversion material to discharge plasma baking so that its surface oxide layer is destructed for dispersion as oxide nanoparticles while baking the nanoparticles of the thermoelectric conversion material each other, for forming the matrix. <P>COPYRIGHT: (C)2013,JPO&INPIT |
