RESEARCH PROGRAM ON SEMICONDUCTING COMPOUNDS FOR THERMOELECTRIC POWER GENERATION AT HIGH TEMPERATURES

Abstract

SEARCH, *Electric power production. Samples of WSe2 and WTe2 were prepared. The material resulting from mixing Ta powder and Se in a 1:4 atomic ratio gave a complex X-ray diffraction pattern indicating a TaSe phase of low crystal symmetry. A compound was prepared which is probably a Laves-type phase of nominal composition Ta31Te8. Difficulties were encountered in producing a Ta-Ge compound in sufficient quantity for measurement because of the large increase in volume during the reaction. An unknown phase was indicated in the reaction material from a 1:4-atom-ratio mixture of Hf and Se. A dark powder obtained from an Re-Se sample reacted at 1200 F for 260 hr may have useful properties as a solid lubricant. Results are presented of Seebeck coefficient and resistivity measurements made on NiAl, TaSb, WTe2, and WSe2.
