Abstract: The thermoelectric properties of Bi-Te binary and Bi2Te3-Sb 2Te3, Bi2Te3-Bi2Se3 ternary alloys with some additional elements, prepared by powder metallurgy has been studied. The effects of particle size, compacting pressure, sintering condition, and an anisotropy of the thermoelectric elements was experimented. The results show that the specimens prepared by powder metallurgy has the figure of merit Z values almost equal to those of specimen of same composition prepared by melting method. The sintered thermoelement has higher ρ value than the melted element, and is therefore suitable for the objects used by low optimum current.
