Polycrystalline bulk β-FeSi2 was prepared by heating a compact body of Fe powder in a Na-Si melt at 1173K for 24 h. The relative density of the bulk sample was 78% of the theoretical density of β-FeSi2. Mn-doped and Co-doped bulk samples were also prepared from compact bodies of Fe powder mixed with Mn and Co powders. The Seebeck coefficients measured for the Mn- and Co-doped samples in the temperature range between 400 and 1000K were +125 to +270 μV/K and -120 to -180 mV/K, respectively.
