Abstract

It has been reported that high figures of merit could be achieved on bismuth telluride grown by T.H.M. (Travelling Heater Method). Further improvements could be obtained for the p-type materials by studying solid solutions formed by bismuth telluride and antimony telluride.

A good knowledge of the ternary phase diagram is necessary to obtain homogeneous ingots by T.H.M..

We present the results of the determination of ternary phase diagram (Bi-Sb-Te). The equilibrium data between liquid and solid alloys Bi8Sb32Te60, Bi9Sb31Te60 and Bi10Sb30Te60 are also reported and it allows their elaboration by T.H.M..

Thermoelectric characterization of ternary samples is carried out as a function of stoichiometric deviations. Measurements of electrical and thermal conductivities as well as Seebeck coefficient were done at room temperature for the Bi8Sb32Te60, Bi9Sb31Te60 and Bi10Sb30Te60 alloys.

The values of the figure of merit remain interesting for the alloys studied and a maximum value of 3.2 10−3 K−1 is reached for the Bi9Sb31Te60 alloy.
