Abstract ABSTRACT Thermoelectric material β-FeSi2 was prepared by the technology of combustion synthesis-heat treatment in this paper, silicon-iron intermetallic phase composition and microstructure were characterized by X-ray diffraction and scanning electron microscopy, and the effects of different contents of Mn and Cu on the synthesis of β-FeSi2 were investigated. The results show that only heat treatment transform α-Fe2Si5 into β-FeSi2; addition of appropriate amount of Mn and Cu can increase β phase yield in product after heat treatment, but separate doping Mn or Cu can not eliminate α phase. When 1.0%Mn and 0.6%Cu meanwhile is added, β phase reach the highest peak, and α-Fe2Si5 completely transform into β-FeSi2; heat treatment can largely refine crystal particle obtained by self-propagating high-temperature synthesis.
