HIGH TEMPERATURE THERMOELECTRIC GENERATOR.
Abstract
A new, thermoelectric alloy with a negative Seebeck coefficient has been investigated, Au-9 w/o Ni. The physical and chemical properties of this alloy are superior to those of constantan used in earlier work as the negative leg and encapsulant for segmented p-type legs of Ta-doped WSe2 and PbTe. The gold alloy has a higher Seeback coefficient than constantan, does not react with Se vapors, and is oxidation resistant. Design of thermoelectric modules has been altered to make use of the new alloy. No change is required in design of the generator. Preparation and processing of WSe2 has been standarized. Some earlier results on modules using constantan are summarized. (Author)
