Abstract: PURPOSE:To provide a method for more easily and practicably producing a material for thermo-electric conversion elements which permits uniform addition of oxygen into alloy powder with an extremely large treatment capacity in respective stages and without requiring high energy by a plasma treatment and eventually has extremely larger thermoelectromotive force without degradation of the thermal electromotive force due to internal segregation at the time of producing the thermo-electric conversion material having a high thermo-electric characteristic by increasing of the thermoelectromotive force and lowering of thermal conductivity. CONSTITUTION:This process comprises producing the powder for the high-characteristic thermo-electric conversion element by heating and holding FeSi2 iron silicide powder at >=920 to <=1500K in an >=15% oxygen-contg. atmosphere. The FeSi2 iron silicide powder is obtd. by pulverizing the material produced by using a rapid solidifying method. Further, the powder material heated and held in the oxygen-contg. atmosphere described above is subjected to solidification molding and is then heated and held to and at >=870 to <=1250K, by which the thermo-electric conversion material having the high thermoelectromotive force is produced.
