CHEAP TECHNIQUE OF MAKING THERMOELECTRIC ELEMENTS BY POWDER METALLURGY METHOD Russian patent published in 2019 - IPC H01L35/34 

FIELD: metallurgy.

SUBSTANCE: invention relates to production of thermoelectric elements. Summary: active material is being pressed, non-sintered pieces are placed in through holes of substrate and sintered. Sintering of the non-sintered pieces and equalization of the substrate and branches of the thermoelectric element are carried out in one working operation, using flat sintering electrodes arranged flat-parallel to the substrate, which approach the substrate as shrinkage of the non-sintered pieces during sintering. At the end of the sintering process, the thickness of the substrate and the length of branches of the thermoelectric element are set by the distance between the electrodes.

EFFECT: possibility of implementation using standard machines and equipment and exclusion of additional processing operation for adjustment of substrate and branches of thermoelectric element.
