THERMOELECTRIC PROPERTIES OF SELENIDES AND TELLURIDES OF GROUPS VB AND VIB METALS AND THEIR SOLID SOLUTIONS

Abstract

IN A STUDY OF THE MoSe2-NbSe2 system, the effects of sintering conditions and of deviations from stoichiometry on resistivity, Seebeck coefficient and density were investigated for the pure compounds and for the 1:1 solid solution. The data reported at this time are limited mostly to roomtemperature measurements and, therefore, of no immediate practical value, since the thermoelectric figure of merit for these materials is poor at temperatures below 400 C. Concurrent work on the construction of a ther oelectric generator for efficiency and life tests dealt with junction fabrication problems on tungsten selenide. Ultrasonic soldering provides an excellent cold junction, while powered iron, sintered under pressure, promises to provide a satisfactory bonding layer between the selenide and an iron connector plate on the hot side.
