Abstract:

Improved procedures in synthesis and in measurements have eliminated unreproducibilities in tantalum-doped tungsten diselenide preparations, giving a well-substantiated Figure of Merit of about 0.5 x 10 to the minus 3 powerdeg in the 500 to 1000 C range. An apparatus for direct efficiency measurements is under construction. It is planned to incorporate tantalum-doped tungsten diselenide p-type in a practical thermoelectric module, cascaded with p-type lead telluride and encapsulated in a ceramic coated constant can which will also serve as the n-leg of the couple. Experimentation with the details of construction is underway. Thermoelectric properties of selenides and tellurides of Group VB and VIB metals and their solid solutions. Construction of a thermoelectric module using tantalum-doped tungsten diselenide.
