<p>A process for producing a thermoelectric material based on two ormore elements selected in the group constituted by Bi, Sb, Te andSe, which process comprises: i) an alloying step wherein determined amounts of the elements Bi, Sb, Te or Se are mixed until an homogenous powdered alloy is obtained; ii) an extrusion step of thepowdered homogenous alloy obtained in the preceding step. The elements Bi, Sb, Te or Se being preferably mechanically mixed in an homogenous powdered alloy. The thermoelectric material, which is obtainable by this process, exhibits improved thermoelectric a ndmechanical properties and is therefore suitable, for example,as cooler, as temperature stabilizer in an electronic device or aspower generator.</p> |
