  • THERMOGENERATOR AND PROCESS FOR PRODUCING A THERMOGENERATOR
    Publication number: 20130255740
    Abstract: The invention relates to a process for producing a thermogenerator (10) comprising a plurality of thermocouples formed of p-type thermoelements (12) and n-type thermoelements (14). A wafer (18), provided with a plurality of holes (20a, 20b) is covered in thermoelectric material powder (22, 24). Pressure (P) is applied to the powder (22, 24) so that it penetrates into the holes (20a, 20b) while heating so as to form a plurality of p-type and n-type thermoelements (12, 14) contained in the wafer (18). The wafer (18) is thinned, the thinned wafer thus forming a matrix (16) in which the thermoelements (12, 14) are contained. While preserving the matrix (16) the p-type thermoelements are connected so as to form thermocouples and the n-type thermoelements are connected so as to form thermocouples, thereby obtaining a thermogenerator (10).

  • Making thermoelectric materials by mechanosynthesis
    Patent number: 8444915
    Abstract: The invention concerns a method for making a thermoelectric element consisting mainly of a crystalline alloy having a cubic structure, the alloy comprising a first constituent having at least a first element selected among the transition metals, a second constituent having at least one element selected among column XIV, XV or XVI of the periodic table, and a third constituent having at least one constituent selected among rare earths, alkalis, alkaline earths or actinides. The method includes making the alloy in the form of nanopowders by mechanosynthesis. The invention also concerns the thermoelectric material obtained by implementing said method.
