  • Mg—Si system thermoelectric conversion material, method for producing same, sintered body for thermoelectric conversion, thermoelectric conversion element, and thermoelectric conversion module
    Patent number: 9627600
    Abstract: Provided are: an Mg—Si system thermoelectric conversion material which exhibits stably high thermoelectric conversion performance; a sintered body for thermoelectric conversion, which uses this Mg—Si system thermoelectric conversion material; a thermoelectric conversion element having excellent durability; and a thermoelectric conversion module. A method for producing an Mg—Si system thermoelectric conversion material according to the present invention comprises a step for heating and melting a starting material composition that contains Mg, Si, Sb and Zn. It is preferable that the contents of Sb and Zn in the starting material composition are respectively 0.1-3.0 at % in terms of atomic weight ratio.
    Type: Grant
