Polycrystalline samples were prepared by a modifies ceramic method. The electrical conductivity, the Seebeck coefficient and the thermal conductivity were measured over a temperature range of 300-800 K. The undoped Co4Sn6Se6 compound was of p-type electrical conductivity and had a band gap E (g) of approximately 0.6 eV. The influenceof transition metal (Ni and Ru) doping on the thermoeletric properties was studied. While the thermal conductivity was significantly lowered both for the undoped Co4Sn6Se6 compound and for the doped conpounds, as compared with the Co4Sb12 binary skutterudite, the calculated ZT values were improved only slightly.
