ABSTRACT:
Thermoelectric legs of useful durability may be prepared by hydrostatic extrusion. In cross-section, the legs may have either circular or non-circular shapes of special usefulness, and the legs may be formed in narrow elongated sizes, which are useful in compact, high-voltage thermoelectric converters.
